  getting error....Can somebody help me how to handle this scenario.

  from this variable Pack Units-jun'11 ....i have to pick  just jun'11.

  Here is error msg:

 

rename

26 ! &vara1=substr(compress(&vara1),length(&vara1),-5);

Proc sql;
select distinct name into  : vara1-:vara3 from contents1 where name not in ('Account Manager','CORPORATE PARENT NAME')
order by VARNUM;
quit;


data final ;

How about:

options validvarname=any;
data test;
"Pack Units-jun'11"n= 'asdasdf';
run;
%let var1= %str(Pack Units-jun%'11) ;
proc datasets library=work memtype=data;
 modify test;
 rename "%unquote(&var1)"n="%scan(&var1,-1,%str(-))"n;
quit;
%put _user_;

with what code do you read the file into SAS?

Whatever it is,  that might have an option to create column names that are easier to work with.

Looks like the existing routine is generating column names that conform to option validvarnane= any;

These are awkward to handle in the macro language but simpler in a data step.

like:

data _null_ ;

  if _n_ = 1 then call execute(' data final ; set sasuser.test12; rename ' ) ;

  set contents  end= eof ;

  where lowcase(name)=: 'pack units-'  ;

  length newA1 $32 ;

  newA1 = scan( name, -1, '-' ) ; *picking out the suffix after the - ;

  call execute( quote(trim(name)) !! 'n  =  ' !! quote( trim(newA1)) !! 'n'  ) ;

  if eof ;

  call execute( ' ; run ;' ) ;

run ;
