The BasePlus package [ver. 1.43.0]

## The BasePlus package [ver. 1.43.0]

### Changes:

Update to [`%getVars()`](https://github.com/SASPAC/baseplus/blob/1.41.0/baseplus.md#getvars-macro-8) and [`%qgetVars()`](https://github.com/SASPAC/baseplus/blob/1.41.0/baseplus.md#qgetvars-macro-15) macros.

New parameter `ignoreCases=` added. It is an *optional* parameter.
It indicates if variables names search should be case insensitive.
With default value `1`, the search *is* case insensitive.

See [documentation](https://github.com/SASPAC/baseplus/blob/main/baseplus.md) for details.

 ## Intro:
 
@@ -6,101 +8,244 @@ A **SAS package** is an automatically generated, single, stand alone *zip* file
 
 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.

 ## Available packages:
-Currently the following packages are available (see the `./packages` directory):
 
-- **SQLinDS**\[2.1\], based on Mike Rhoads' article *Use the Full Power of SAS in Your Function-Style Macros*. The package allows to write SQL queries in the data step, e.g.
-```
-data class;
-  set %SQL(select * from sashelp.class order by age);
-run;
-```
+This section presents some examples of available SAS packages.
 
-- **DFA** (Dynamic Function Arrays)\[0.2\], contains set of macros and FCMP functions which implement: a dynamically allocated array, a stack, a fifo queue, an ordered stack, and a priority queue, run `%helpPackage(DFA,createDFArray)` to find examples.
-- **macroArray**\[0.3\], implementation of an array concept in a macrolanguage, e.g. 
-```
-  %array(ABC[17] (111:127), macarray=Y); 
+**(!)** Since *September 2022* the default and **official** location for packages is **SASPAC - the SAS Packages Archive** located under: [`https://github.com/SASPAC`](https://github.com/SASPAC) where each package is stored as a separate repository with historical versions.
 
-  %do i = 1 %to 17; 
-    %put &i.) %ABC(&i.); 
-  %end;
+**(!)** For "backward compatibility"/historical point of view the following packages are also available under the `./packages` directory in this repository.
 
-  %let %ABC(13,i) = 999; /* i = insert */
+Packages:
 
-  %do i = 1 %to 17; 
-    %put &i.) %ABC(&i.); 
-  %end;
-```
+- **SQLinDS**
 
-- **BasePlus**\[0.5\] adds a bunch of functionalities I am missing in BASE SAS, such as:

+## 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)
+License: MIT
+Encoding: UTF8
+
+Required: "Base SAS Software"
+
+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
+)
+```

+%include packages(SPFinit.sas);
+
+%loadPackage(HelloWorld)
+
+%HelloWorldMacro(7)

+
+
+*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.

+
+ 
+## >>> `%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.

+### SYNTAX: ###################################################################
+
+The basic syntax is the following, the `<...>` means optional parameters:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%GSM( 
+   path
+ <,trim=0>
+ <,cmplib=work.generateMacros>
+ <,source2=>
+ <,outpath=>
+ <,encodingRestricted=>

+ <,lineEnd=>
+ <,encrypt=>
+)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+
+1. `path`               - *Required*, indicates a directory which contains files with macros.
+                          Only files with `sas` extension are used.
+
+* `cmplib=`             - *Optional*, the default value is `work.generateMacros`. 
+                          Names the dataset which will contain generated functions. 
+
+* `source2=`            - *Optional*, the default value is null. 
+                          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.
+
+* `trim=`               - *Deprecated*, the default value is `0`.
+                          *Kept for backward compatibility.*
