yabwon 7c1d58c165 macroArray package, version 0.6
macroArray package, version 0.6:

New feature of the `%array()` macro. If the `macarray` parameter of the `%array()` macro is set to `M` then for a given array name the macro symbols table is scanned for macrovariables with prefix like the array name and numeric suffixes. Then the minimum and the maximum index is determined and all not existing global macrovariables are created and a macro is generated in the same way as it is generated for the `Y` value.

Documentation updated.

SAS Packages:

To get started with SAS Packages try this Getting Started with SAS Packages presentation (see the ./SPF/Documentation directory).

Available packages:

Currently the following packages are available:


  • SQLinDS[2.2], 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 age, name, weight, height 
    from sashelp.class 
    order by age
    );
    
    WH = weight + height;
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.
%createDFArray(ArrDynamic, resizefactor=17); 

data _null_;
  call ArrDynamic("Allocate", -2, 2);

  do i = -2 to 2;
    call ArrDynamic("Input", i, 2**i);
  end;

  L = .; H = .;
  call ArrDynamic("Dim", L, H);
  put L= H=;

  call ArrDynamic("+", 3, 8);
  call ArrDynamic("+",-3, 0.125);
  call ArrDynamic("Dim", L, H);
  put L= H=;

  Value = .;
  do i = L to H;
    call ArrDynamic("O", i, Value);
    put i= Value=;
  end;
run;

  • macroArray[0.6], implementation of an array concept in a macro language, e.g.
  %array(ABC[17] (111:127), macarray=Y); 
  
  %macro test();
    %do i = 1 %to 17; 
      %put &i.) %ABC(&i.); 
    %end;
  %mend;
  %test() 
  
  %let %ABC(13,i) = 99999; /* i = insert */

  %do_over(ABC, phrase=%nrstr( 
      %put &_i_.%) %ABC(&_i_.); 
      ),
      which = 1:H:2
  );

  • BasePlus[0.7] 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, pattern = ght$, sep = +, varRange = _numeric_);
