Get the timestamp of the programs from the load module

Hi,

I have a requirement to get the timestamp of the programs from the load module.

for that i need to read the load module. it can be done by rexx or jcl or any other means.

Please let me know how to do it.

I would first use ISPF browse to make sure that a time stamp is in there.

Then perhaps use AMBLIST to format the load module and process the AMBLISTing with rexx to search for the values you want. The timestamp might not be in the same location all of the time.

The compiler/assembler leaves a version/timestamp in the compiled code and (IIRC) the binder/linkage editor does the same.
There are several free/pay for/included programs that can scan a load module PDS and extract the info into whatever format you are willing to mine it for....

COBOL generates a time stamp that is version specific for the compile date and time. When the program runs through the binder (or linkage editor depending on system) a packed decimal date and time stamp are placed on a particular record (length 22 hex perhaps -- it's been a while).

I agree that we get time stamp..I have used Amblist to get the timestamp.
I need to read the load like reading the file..
I tried with rexx and jcl but not able to do it..

please let me know the way to read it

When you give up trying to read it, try this:

ramakrishnan: I just checked the REXX manual and it specifically states that EXECIO will not read undefined format files -- and load modules are undefined format. If your requirement really is to read the load module, you cannot use REXX to do so.

Is there any faclity in jcl or cobol to read the load module and write it to a vb or fb file?

The simplest solution for your requirement is to do as Pedro suggested. Write a REXX program that allocates the files needed for AMBLIST, invokes AMBLIST, and then processes the output. This way, AMBLIST does the hard bit and you get the results in one execution of your REXX program. The fact that AMBLIST is doing the work "under the covers" is transparent.

Here's a snippet you could work from
