you're lucky to be on that platform
( well maybe ;-) )
if you can allocate the ddnames that TELON needs as filename statements, then [pre] PROC TELON ;
will run that external program.
If it writes an external file, when that PROC TELON finishes, you can parse that output in a data step, like [pre] data got_IT;
infile sysprint truncover ;
input @'required string' foundit $char100. ;
Alternatives exist. However, I found it very useful for PROC FTP, and an easy test should be IEBGENER.
Of course one gotcha:
Your TELON will need DDNAMES already in use by a normal SAS session. Fortunately there are ways to start SAS with unusual ddnames, like the SYSIN=SASIN option which directs SAS to read statements from DDNAME SASIN.
