array: Way of get variables in array taken together (not one by one)

t_ar_taat — Sat, 22 Oct 2016 15:01:46 GMT

I'm looking for a way to get the contents/variables of array.
For example

data work.chars;
 char1 = "aa";
 char2 = "bb";
 output;
run;

data work.test2;
 length _GETNAMES $40. ;
 set work.chars;
 array ch _CHARACTER_;
 do over ch;
       _GETNAMES = vname(ch);
         if _GETNAMES ^= "_GETNAMES" then put _GETNAMES;
 end;
run;

We know that array "ch" has variable cha1 char2 inside,

Is there a way to get it with 1 time?

The result is "cha1 char2" or "cha1,char2".

So as to allow “vlabel” function to get the content of label in the variable.

I'm searching a function or way to catch contents of array.

Sincerely.

You can build the list this way:

data work.chars;
 char1 = "aa";
 char2 = "bb";
 output;
run;

data work.test2;
if 0 then set work.chars;
array ch _CHARACTER_; /* Declared before creating variable _GETNAMES */
length _GETNAMES $40 ;
do i = 1 to dim(ch);
   _GETNAMES = catx(", ", _GETNAMES, vname(ch{i}));
    end;
put _GETNAMES;
output;
stop;
run;
