Hi,

Try something like the following :-

   if _n_=1 then do;
      retain rx;
      rx = rxparse(
         "($C+) to ''''&PREFIX.==''''" );
   end;
   call rxchange( rx, 999, string);

Kind regards
== Jeff

I have a string of words separated by space(s) and would like each
word to be quoted by a single quote character ( ' ). Also in addition
to this I would like each word to prefix by a text constant . I would
like to do this with RXPARSE with a macro function.

/* example */
%macro qword(string=, prefix=);
    ...
%mend;


%put %qword(string = jan feb      march, prefix=2003);

/* the result of this should be */
'2003jan' '2003feb'      '2003march'


Many Thanks
