Renaming variable w/ macros

jmmedina25 — Fri, 29 Mar 2019 17:01:01 GMT

Hi! I'd like to rename variables using a macro-

So I have variables for 1-10 programs and I need to rename them the same name based on their suffix but I need to do the rename given prefix= prog1-prog10.

Example:

Prog1_ProgramCat_TEXT= prog_name

Prog2_ProgramCat_TEXT=prog_name

Prog3_ProgramCat_TEXT=prog_name

.. all the way to the prefix= Prog10_

(All info is contained in variable answers; Please let me know if you need more data info)

So here's my crazy attempt to make a code for this:

%macro rename(prgname=, prgchall=, prgven=, prgcost=, prgday=, prgdur=, prgdurun=, prgeval=, prgevent=, prgnum=, prgcat=, prgfreq=, prgsite=, prgstart=, prgconsid=);
data programcondensing;

	set WORK.TestExport (keep=agency prog1_: prog2_: prog3_: prog4_: prog5_: prog6_: prog7_: prog8_: prog9_: prog10_: responseid);
		 %rename &prgconsid = prog_considerations
				&prgname= prog_name
				&prgchall = prog_challenges
				&prgven = prog_vendor
				&prgcost= prog_cost
				&prgday = prog_date
				&prgdur = prog_duration
				&prgdurun = prog_duration_unit
				&prgeval = prog_eval
				&prgevent = prog_type
				&prgnum = prog_Num
				&prgcat = prog_cat
				&prgfreq = prog_freq
				&prgsite = prog_site
				&prgstart = prog_start;
			
run;
%mend rename;
options mlogic;

%rename (prgname=:ProgramCat_TEXT, prgchall= :_2, prgven= :_4, prgcost=_5, prgday=:_date_1, prgdur=:_duration, prgdurun=:_durationunit, prgeval=:_evalyesno, prgevent=:_eventtype, prgnum=:_numparticipants, prgcat=:_programcat, prgfreq=:_programfreq, prgsite= :_site_1, prgstart= :_starttime_1, prgconsid=:_1)

Please help:)

Macro? Not needed. Macro variable? YES!

Your problem description isn't entirely clear, you can't rename all of them to prog_name as shown in the example

Here's the general outline of how to do this.

proc contents data=have noprint out=_contents_;
run;
proc sql noprint;
    select cats(name,'=','prog',scan(substr(name,4),1,'_'))
        into :renames separated by ' ' from _contents_
        where name eqt 'prog' and name ? '_ProgramCat_TEXT';
quit;
proc datasets library=work nolist;
    modify have;
    rename &renames;
    delete _contents_;
run;
quit;
