Is there any subroutine for finding the logical record length of the file.? What's the logic on how to find the lrecl of the file at run time?

Try to get to the JFCLRECL field of the JFCB data area.

Here's a roundabout way:

SAS includes much file info in the SAS log.

1. run a SAS program to read one rec from the file
2. send the SAS log to a file, e.g., &&SASLOG
3. read the SAS log and find the line with the LRECL

Well, simpler way is to add a REXX step which calls LISTDSI. SYSLRECL will contain the record length.
