Is there a standard method by which I can code a COBOL program to report out the dataset names of its input and output files? I've been looking thru the manuals but I can't seem to find anything. Any suggestions would be appreciated.

Why not parse the JCL that executes the COBOL program? Use REXX, DFSORT, etc. The JCL itself can be found out using 3.14 _________________ ALL opinions are welcome.

Pudah,
I am sorry to say I could not find my source. I guess it is in one of my PDS which was migratted and eventually got deleted .However to redeem myself I have the following SAS code which will get you the DSNAME for the DDNAME.
Code:
DATA DB2VOLS;
LENGTH XFILE $ 44;
INFILE DDNAME1 FILENAME=XFILE END=EOF;
INPUT @05 TYPE $CHAR2.
@25 SSID $CHAR4.
@25 DSN $CHAR44.
@79 VOL $CHAR6.
;
IF EOF THEN PUT 'INPUT FILE = ' XFILE;
$$
The above code will give the DSNAME associated to DDNAME1.

Hi Pudah,
Here's a pgm written by Gilbert St. Fleur. It does what you want plus much more.

CBL NOMAP,NOLIST,NOOFFSET,NOXREF
