Subject:      GDG exists
Content-Type: text/plain; charset=us-ascii

Hi all,
 
I am trying to use sas to determine if a GDG exists after reading in a
parm file of required files for another job to run. I'm creating a
varable called File1 that contains the value of the inputs from the parm
file. Then I'm doing the following:
 
Call symput('File2','File1');
Filename XFILE '&File2';
    If &sys99err = '1708' then exists = 'N';
    else exists = 'Y';
 
What I can't figure out is why this doesn't work. If I replace '&File2'
with something like 'Test.File.Exists(0)' and the file doesn't exist, I
get the expected error. But if I try to use a variable instead with the
Filename command, nothing happens.
 
Any suggestions or better ways to use SAS to determine if a GDG exists
or not? Thanks.
