+
+[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.wuss.org/wuss-2023-conference-proceedings/ "Article about the idea GSM")
+
+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.
+
+
+*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-1"></a> ######
+ 
+## >>> `%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
+as encrypted code which allow to share the macros
+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 and th emacro code has to be written properly. 
+See the example:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%macro secretMacro(x) / SECURE; %* <- the secure option *;
+  <... secure 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.

+ <,source2=>
+ <,outpath=>
+ <,encodingRestricted=>
+ <,secret=>
+ <,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.*
