regex in SAS

[aaaaa34]

Hi,

How can I delete "qt" in 0,023qt using regex?

data test;
   string="0,023qt";
   newstring=prxchange('s/qt//', -1, string);
run;

Is it possible to use PRXPARSE? I'd like to use it in my code.

The PRXPARSE Function simply compiles the rexex for later use. Sure you can use it, but you don't really benefit from it, since PRXCHANGE accepts an actual regular expression and not only the compiled rexex id

data test;
   string="0,023qt";
   rx=prxparse('s/qt//');
   newstring=prxchange(rx, -1, string);
run;
