I am new to SAS.
What I want to do is to read in an xls file, then either update the existing xls file or create a new xls file. But it seems only created a new xls file, didn't update the records.
Here is my code:
filename input "replace.xls";
filename output "replaceout.xls";
data testdata;
infile input recfm=f ignoreDOSeof;
input ;
RegularExperssionId=prxparse('s/M[. ]/MA/');
call prxchange(RegularExperssionId, -1, input);
file output recfm=f;
put _infile_;
run;
Thanks for all your help. And do let me know if I post the message in the wrong group.
