SAS_PACKAGES/packages

Available packages:

Currently the following packages are available:

• 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;

• 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); 

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

  %let %ABC(13,i) = 999; /* i = insert */

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

• BasePlus[0.5] adds a bunch of functionalities I am missing in BASE SAS, such as:

call arrMissToRight(myArray); 
call arrFillMiss(17, myArray); 
call arrFill(42, myArray); 

rc = delDataset("DataSetToDrop"); 

string = catXFn("date9.", "#", myArray);

format x bool.;

%put %getVars(sashelp.class, patern = ght$, sep = +, varRange = _numeric_);

• dynMacroArray[0.2], set of macros (wrappers for a hash table) emulating dynamic array in the data step (macro predecessor of DFA)
