Available packages:

Currently the following packages are available:

• SQLinDS, 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 datastep, e.g.

data class;
  set %SQL(select * from sashelp.class ordered by age);
run;

• DFA (Dynamic Function Arrays), 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, implementation of an array concept in a macrolanguage, e.g.

  %array(ABC[17] (111:127), macarray=Y); 

  %do i = 1 %to 17; 
    %put &i.) %ABC(&i.); 
  %end;

  %let %ABC(13,M=i) = 999;

  %do i = 1 %to 17; 
    %put &i.) %ABC(&i.); 
  %end;

• dynMacroArray, set of macros (wrappers for a hash table) emulating dynamic array in the datastep (macro predecessor of DFA)
