 The *purpose of a package* is to be a simple, and easy to access, code sharing medium, which will allow: on the one hand, to separate the code complex dependencies created by the developer from the user experience with the final product and, on the other hand, reduce developer's and user's unnecessary frustration related to a remote deployment process.

+## The "Hello World" Package
+
+---
+
+This is a "Hello World" example on how to build your first package with help of the SAS Packages Framework.
+
+We will generate a `HelloWorld` package.
+
+Follow the step by step instruction below.
+
+---
+
+`Step 1.` Create a folder for the framework e.g.,
+          `/home/<myUserName>/SASpackages` or `C:/SASpackages`
+
+`Step 2.` Run the following code to install The SAS Packages Framework
+          in the folder you created in the `Step 1.`
+
+```sas
+filename packages "<put/folder/from/the/step/one/here>";
+filename SPFinit url "https://raw.githubusercontent.com/yabwon/SAS_PACKAGES/main/SPF/SPFinit.sas";
+%include SPFinit;
+%installPackage(SPFinit)
+```
+ 
+Check out the *log* to verify if the `Step 2.` was successful.
+If it was - then continue.
+
+
+`Step 3.` Create a folder for the content of the package we will generate e.g.,
+          `/home/<myUserName>/HelloWorldPackage` or `C:/HelloWorldPackage`
+
+`Step 4.` Inside the directory from the `Step 3.` create two sub-folders: `01_formats`
+          and `02_macros`. Remember to use *lower case letters* only!     
+
+`Step 5.` Inside the `01_formats` folder create a `helloworldformat.sas` file.
+          Remember to use lower case letters in the file name. Copy-paste below code
+          into that file:
+
+```sas
+/*** HELP START ***//*
+ This is a help info for the `HelloWorldFormat.` format.
+ 
+ Category *other* is marked with exclamation mark (`!`).
+*//*** HELP END ***/
+
+value HelloWorldFormat
+  1 = " Hello"
+  2 = " SAS"
+  3 = " Packages"
+  4 = " World"
+  other = "!"
+;
+```
+
+`Step 6.` Inside the `02_macros` folder create a `helloworldmacro.sas` file.
+          Remember to use lower case letters in the file name. Copy-paste below code
+          into that file:
+```sas
+/*** HELP START ***//*
+ This is a help info for the `%helloWorldMacro()` macro.
+ 
+ Macro has the following parameter(s):
+ - `n` - *Required*, provides number of loop iterations.
+ 
+*//*** HELP END ***/
+
+%macro HelloWorldMacro(n);
+  data _null_;
+    do i = 1 to &n.;
+      put i HelloWorldFormat. @; 
+    end;
+  run;
+%mend HelloWorldMacro;
+```
+
+
+`Step 7.` Inside the directory from the `Step 3.` create a `description.sas` file. 
+          Remember to use lower case letters in the file name. Copy-paste below text
+          into that file, adjust lines 5 and 6:    
+```txt
+Type: Package
+Package: helloWorld
+Title: My Hello World SAS package.
+Version: 1.0
+Author: <myFirstname> <myLastname> (my@mail.com)
+Maintainer: <myFirstname> <myLastname> (my@mail.com)

+
+DESCRIPTION START:
+### My "Hello World" SAS package ###
+
+The "Hello World" is my first SAS package and 
+for sure it will not be the last package one!
+
+Using packages is a good idea!
+DESCRIPTION END:
+```
+
+`Step 8.` Execute the following code and check the log 
+          to read the `%generatePackage()` macro help info.
+
+```sas
+%generatePackage()
+```
+
+`Step 9.` Execute the following code using the folder 
+          from the `Step 3.` and check the log to see how 
+          the process of package generation went.
+
+```sas
+%generatePackage(
+  filesLocation=<put/folder/from/the/step/three/here>
+ ,markdownDoc=1
+)
+```
+
+`Step 10.` See the information in the output window and in the log.
+           The `WARNING:[License] No license.sas file provided, default (MIT) licence file will be generated.` can be ignored.
+
+`Step 11.` Check the directory from the `Step 3.` and look for the `helloworld.zip` package file and `helloworld.md` documentation file.
+
+---
+
+`Step 12.` Start a new SAS session, run the following code, and investigate the log:
+
+```sas
+filename packages ("<put/folder/from/the/step/one/here>" "<put/folder/from/the/step/three/here>");
+%include packages(SPFinit.sas);
+
+%loadPackage(HelloWorld)
+
+%HelloWorldMacro(7)
+```

+##      This is short SAS Packages Framework help information <a name="helpinfo"></a>

 A **SAS package** is an automatically generated, single, stand alone *zip* file containing organised and ordered code structures, created by the developer and extended with additional automatically generated "driving" files (i.e. description, metadata, load, unload, and help files). 

 The *purpose of a package* is to be a simple, and easy to access, code sharing medium, which will allow: on the one hand, to separate the code complex dependencies created by the developer from the user experience with the final product and, on the other hand, reduce developer's and user's unnecessary frustration related to a remote deployment process.

+## Utility macros generated during loading a package ###########################
+
+If a package contains IML modules or CASL user defined functions additional 
+utility macros for IML Modules and CASL UDFs are generated when package is loaded. 
+
+Macros are generated with the following names: `%<packageName>IML()` and `%<packageName>CASLudf()`. 
+
+Their purpose is to make loading of Modules or UDFs (with potentially multiple 
+dependencies) easy in Proc IML and Proc CAS. 
+
+Run them, accordingly, as the first line in the Proc IML or Proc CAS to access the package content. 
+For Proc IML the use is as follows:
+~~~~~~sas
+  proc IML;             
+    %<packageName>IML()
+   
+    <... your code using IML modules from the package ...>
+  quit;
+~~~~~~
+For Proc CAS the use is as follows:
+~~~~~~sas
+  proc CAS;             
+    %<packageName>CASLudf()
+   
+    <... your code using CASL UDFs from the package ...>
+  quit;
+~~~~~~
+
+If a utility macro is generated appropriate note and a code snippet 
+is printed in the log of the package loading process.
+
+In 99% cases macros are used with default parameters values but, 
+in case when deeper insight about macros parameters is needed, 
+help info is printed in the log when the following code is run:
+~~~~~~sas
+  %<packageName>IML(list=HELP)
+~~~~~~
+or
+~~~~~~sas
+  %<packageName>CASLudf(list=HELP)
+~~~~~~
+
+If created, those macros are automatically deleted when the `%unloadPackage()` macro is run.

+
+ By *default* additional content is not deployed automatically e.g., 
+ from security point of view, or production job doesn't need it to run, etc. 
+ But if there is a need for it there are three ways to get it:
+
+ - The first one ("by-the-book"), and also the recommended one. The additional 
+   content is extracted during the automatic installation process using the 
+   `\%installPackage()` macro. For this to work the `loadAddCnt=` parameter 
+   has to be set to `1`. The additional content is extracted to the 
+   `<packageName>_AdditionalContent` directory into the same location where 
+   the package is installed i.e., inside `packages` fileref location.
+ - The second one ("by-the-work"), when the additional content is extracted 
+   during the loading process with the `\%loadPackage()` macro. For this to 
+   work also the `loadAddCnt=` parameter has to be set to `1`. The additional 
+   content is extracted to the `<packageName>_AdditionalContent` directory 
+   inside the `Work` library location.
+ - The third one ("by-the-user"), when the additional content is extracted 
+   with dedicated `%loadPackageAddCnt()` macro. By default the additional 
+   content is extracted to the `<packageName>_AdditionalContent` directory 
+   inside the `Work` library location too, but it can be altered by changing 
+   the `target=` parameter, which indicates the location.
+
+ If done "by-the-book", or "by-the-user" with `target=` parameter, the 
+ additional content is not automatically deleted when SAS session ends, 
+ in this case the "additionals" have to be deleted manually by the User.
+
+

+# The GSM package [ver. 0.22.1] <a name="gsm-package"></a> ###############################################
+
+The **GSM** (a.k.a. *Generate Secure Macros*) package allows
+to create secured macros stored in SAS Proc FCMP functions.
+The dataset with functions can be shared and allows to generate 
+macros without showing their code.
+
+The GSM package is basically an automated version of the following:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+proc fcmp outlib = work.gsm.secure ENCRYPT;
+  function generateMacro() $;
+    rc = RESOLVE('
+      %macro secretMacro(x) / SECURE;
+        data test;
+         a = "&x.";
+        run;
+      %mend;
+    ');
+    return (rc);
+  endsub;
+run;
+
+/* share work.gsm dataset */
+options cmplib = work.gsm;
+data _null_;
+  rc = generateMacro();
+  put rc=;
+run;
+
+/* enjoy */
+%secretMacro(42)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+See examples for more details.
+
+[Recording of presentation with "how it works" description (in Polish)](https://www.youtube.com/watch?v=LtaWPe2sgRY&t=1s "YouTube").
+
+[The WUSS 2023 Conference article describing the idea](https://www.lexjansen.com/wuss/2023/WUSS-2023-Paper-189.pdf "Article about the idea GSM")
+
+
+*How to use it:* 
+ - Copy all files with your secured macros code into a directory. 
+   Best approach is to have one file for one macro.
+ - Copy a path to the directory.
+ - Run the following code:
+   ```
+   %GSM(<the path to directory>, cmplib=<name of the dataset>)
+   ```
+ - Share generated `ZIP` file (unzip and run the code).
+ 
+**Limitations:** 
+ - Single macro file cannot be longer than 32760 bytes.
+ 
+ - Multiline text variable. Consider the following code text file:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+%macro~test()/SECURE;~#@
+data~test;~#@
+a~=~"abc~#@
+~#@
+def";~#@
+put~a~hex20.;~#@
+run;~#@
+%mend~test;~#@
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+where `~` symbols the space character, 
+`#` symbols the carriage return (`0D`), 
+and `@` symbols the line feed (`0A`).
+The code file is scanned and inserted into 
+the `resolve()` function argument in a "byte by byte"
+fashion hence also the "end of line" characters are included.
+As the result value of variable `a` will be: 
+
+`a = "abc~#@~#@def"`. 
+
+If you want to use the `GSM` package avoid 
+such "style" of coding in your macros.
+
+

+
+Package contains: 
+  1.   macro      gsm 
+  2.   macro      gsmpck_makefcmpcode

+## >>> `%GSM()` macro: <<< <a name="gsm-macro"></a> #######################
+
+The `%GSM()` macro is the main macro of 
+the **GSM** (a.k.a. *Generate Secure Macros*) package. 
+
+It converts a list of macros provided by the user into
+a data set of the Proc FCMP functions. The macros are stored
+in functions are encrypted which allow to share them without 
+showing their code. *Important* thing is that macros provided 
+by the user *has* to be "secure", i.e. the `secure` option has to 
+be added to the macro definition. See the example:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%macro secretMacro(x) / SECURE; /* <- the secure option */
+  <... some code ...>
+%mend secretMacro;
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+As a result a zip file, containing dataset with functions and 
+code to be executed on site, is generated.
+
+Since encrypted code is stored in a SAS dataset it has
+no limitation in sharing between operating systems (like catalogs have).
+
+*Limitation:* Due to the `Resolve()` function limitations 
+ a single macro file cannot be longer than 32760 bytes.
+
+*Notes:* 
+- All macros have to have the `secure` option added, i.e. `%macro aMacroname(...) / SECURE ;`.
+- During the execution a test macro, named `%GSMpck_dummyMacroForTests()`, is generated.
+- The `%GSM()` macro calls the `%GSMpck_makeFCMPcode(...)` macro internally.

+                          Indicate if `%includ`-ed files are printed out.
+                          Any value other than null enables printing.
+
+* `outpath=`            - *Optional*, the default value is set the same as the `path`.
+                          Points a directory in which a result (a zip file) is generated.
+
+* `encodingRestricted=` - *Optional*, the default value is `0`.
+                          If set to 1 then if User session encoding is different from 
+                          encoding of the session which generates the dataset then 
+                          the generateMacros() function will not execute macro code.
+
+* `secret=`             - *Optional*, the default value is null, in such case the 
+                          secret is generated from the `sha256(datetime(), hex32.)` function 
+                          and is printed in the log. When not null then should be
+                          alphanumerical constant. Non-alphanumerical characters are removed.
+                          Required to execute the `resolve()` function. 
+                          User who do not know the value will not be able
+                          to run the `_maxro_XX_()` function.
+
+* `lineEnd=`            - *Optional*, the default value is `0D0A`, indicates which of:
+                          line feed, carriage return, or both, or a space be inserted 
+                          at the end of line in the intermediate code file that is generated.
+                          Value has to be hexadecimal code (_NOT_ null),
+                          since the value is resolved as `"&lineEnd."x`, so use e.g.
+                          `0A` for line feed, `0D` for carriage return, 
+                          `0D0A` for both, and `20` for space.
+
+* `encrypt=`            - *Optional*, the default value is `ENCRYPT`. 
+                          Indicate if `FCMP` functions generated by the package 
+                          are encrypted. Value has to be either empty or `ENCRYPT`,
+                          all other are converted to default. The option is 
+                          dedicated for debugging, keep the default value 
+                          for production use.

+## >>> `%mcDictionary()` macro: <<< <a name="mcdictionary-macro"></a> #######################
+
+The `%mcDictionary()` macro provided in the package 
+is designed to facilitate the idea of a "macro dictionary" 
+concept, i.e. *a list of macrovariables with common prefix 
+and suffixes generated as a hash digest* which allows 
+to use values other than integers as indexes.
+
+The `%mcDictionary()` macro allows to generate other macros 
+which behaves like a dictionary. See examples below.
+
+The `%mcDictionary()` macro executes like a pure macro code.
+
+### SYNTAX: ###################################################################
+
+The basic syntax is the following, the `<...>` means optional parameters:
+~~~~~~~~~~~~~~~~~~~~~~~sas
+%mcDictionary(
+   H
+  <,METHOD>
+  <,DS=>
+  <,K=Key>
+  <,D=Data>
+)
+~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+
+1. `H`      - *Required*, a dictionary macro name and a declaration/definition, 
+              e.g. `mcDictionary(HT)`. It names a macro which is generated by
+              the `%mcDictionary()` macro. Provided name cannot be empty 
+              or an underscore (`_`). No longer than *13* characters.
+
+2. `METHOD` - *Optional*, if empty (or DECLARE or DCL) then the code of 
+              a macro dictionary is compiled.
+              If `DELETE` then the macro dictionary named by `H` and all 
+              macrovariables named like "`&H._`" are deleted.
+
+* `DS=`     - *Optional*, if NOT empty then the `&DS.` dataset is used to 
+              populate dictionary with keys from variable `&K.` and data
+              from variable `&D.` Works only during declaration.
+
+* `K=`      - *Optional*, if the `&DS.` is NOT empty then `&K.` holds a name of
+              a variable which keeps or an expression which generates keys values. 
+              Default is `Key`.
+
+* `D=`      - *Optional*, if the `&DS.` is NOT empty then `&D.` holds a name of
+              a variable which keeps or an expression which generates data values. 
+              Default is `Data`.

+
+### THE CREATED MACRO `%&H.()`: ####################################################
+
+The created macro imitates behaviour of a dictionary. 
+
+The basic syntax is the following, the `<...>` means optional parameters:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%&H.(
+  METHOD
+  <,KEY=> 
+  <,DATA=>
+)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+
+1. `METHOD` - *Required*, indicate what behaviour should be executed. 
+              Allowed values are:
+                - `ADD`, adds key and data portion to the macro dictionary,
+                   *multiple data portions* are NOT available for one key.
+                - `FIND`, tests if given key exists in the macro dictionary
+                   and, if yes, returns data value associated with the key.
+                   For multiple data portions see the `data=` parameter.
+                - `CHECK`, returns indicator if the key exists in dictionary.
+                - `DEL`, removes key and data portion from the macro dictionary.
+                - `LIST`, prints out a dictionary to the log. 
+                - `CLEAR` removes all data and keys values.
+
+* `KEY=`    - *Optional*, provides key value for `ADD`, `FIND`, `CHECK`
+              and `DEL` methods. 
+              Leading and trimming spaces are removed from the value.
+              The `MD5(...)` function is used to generate the hash.
+              Default value is `_`.
+
+* `DATA=`   - *Optional*, provides data value for the `ADD` method. 
+              Default value is blank.
+
+
+When macro is executed and when data are added the following types of 
+*global* macrovariables are created:
+- `&H._########_K`,
+- `&H._########_V`,
+- `&H._KEYSNUM`.
+
+The `#` represents value generated by the `MD5(...)` function for the given key.
+
+The first type keeps information about the key.
+
+The second type keeps information about the value of a given key
+
+The third type keeps the number of unique values of the key.
+
+See examples below to see use cases.

+### EXAMPLES AND USECASES: ####################################################
+
+**EXAMPLE 1.** Simple concatenation of elements:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%array(a[*] x1-x3 (1:3))
+%array(b[*] x1-x5 (11:15))
+
+%put _user_;
+
+%zipArrays(a, b);
+%put _user_;
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+**EXAMPLE 2.** Shorter list is "reused":
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%array(a[6] (1:6))
+%array(b[3] (10 20 30))
+
+%zipArrays(a, b, result=A_and_B, macarray=Y);
+%put %do_over(A_and_B);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+**EXAMPLE 3.** Use of the `operator=`:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%array(c[0:4] (000 100 200 300 400))
+%array(d[2:16] (1002:1016))

+%put (%do_over(C_plus_D));
+
+%put %C_plus_D(1);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+**EXAMPLE 4.** If one of array names is empty or an array does not exist:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%array(a[6] (1:6))
+%array(b[3] (10 20 30))
+
+%zipArrays(a, );
+%zipArrays(, b);
+
+%zipArrays(a, z);
+%zipArrays(z, b);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+**EXAMPLE 5.** Use of the `function=`:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%array(one[3] A B C, vnames=Y)
+%array(two[5] p q r s t, vnames=Y)
+
+%zipArrays(
+ one
+,two
+,function = catx
+,argBf = %str( )
+,format = $quote.
+,macarray=Y
+)
+%put %do_over(onetwo);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+**EXAMPLE 6.** To reuse or not to reuse, or maybe Cartesian product:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%array(e[3] (10 20 30))
+%array(f[2] (5:6))
+
+%zipArrays(e, f, reuse=n,  operator=+, macarray=Y, result=_noReuse);

+
+%put %do_over(_noReuse);
+%put %do_over(_yesReuse);
+%put %do_over(_cartProdReuse);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+**EXAMPLE 7.** Use middle argument:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%array(yr[3] (2018:2020))
+%array(mth[12] (1:12))
+
+%zipArrays(mth, yr, argMd=5, function=MDY, format=date11., macarray=Y);

+## >>> `%sortMacroArray()` macro: <<< <a name="sortmacroarray-macro"></a> #######################  
+
+The sortMacroArray() macro
+allow to sort elements of a macroarray. 
+
+The **limitation** is that sorted values are limited to 32767 bytes of length.
+
+See examples below for the details.
+
+### SYNTAX: ###################################################################
+
+The basic syntax is the following, the `<...>` means optional parameters:
+~~~~~~~~~~~~~~~~~~~~~~~sas
+%sortMacroArray(
+    array
+  <,valLength=>
+  <,outSet=> 
+  <,sortseq=>
+)
+~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+
+1. `array`             - *Required*, name of an array generated by the `%array()` macro.
+
+* `valLength = 32767`  - *Optional*, default value is `32767`, 
+                          maximum length of a variable storing macrovariable data.
+                          (the reason of 32767 limitation) 
+
+* `outSet    = _NULL_` - *Optional*, default value is `_NULL_`,
+                          an optional output dataset name. 
+
+* `sortseq  =`         - *Optional*, default value is `LINGUISTIC(NUMERIC_COLLATION = ON)`,
+                          sorting options for use in an internal `Proc SORT`.
+
+### EXAMPLES AND USECASES: ####################################################

+
+options mprint;
