I wonder if you've been reading these posts.

CA Technologies (or whatever they're calling themselves this week) gets the big bucks for their JCL analyzer, as do vendors of competitive products for a reason, and it ain't because it's easy!

here is the link to a working jcl scanner/parser/reformatter
http://ibmmainframes.com/about32494.html

as is now is working using open object rexx or regina rexx on a pc
the original was written as an edit macro
should be easy to review it to report it back to the tso environment
cheers

Hi,

I need some help in retrieving a dataset names.

the code snippet I provided can extract also the dataset names!
but naturally You did not care to read it and try to understand it!

also no reason to post the same question multiple times on different forums!
given that the object rexx help forum is not the right place to ask this kind of questions!
cheers

Am just trying to work on my task taking one step at a time with the help of you guys.

HI,

I need to retrieve the data from spool corresponding to ddname & step name..
When am trying to do it say "SYSIN" is my ddname & "TSCRACTH" is my step name..There are more than one SYSIN so the data i need is corresponding to TSCRACTH stepname, but it is getting retrieved from the first SYSIN only..

Here is the code i have tried..

/***************REXX**************/
ADDRESS TSO
"alloc f(isfin) tracks space(1) reu"            /* used by sdsf     */
"alloc f(isfout) new delete reu " ,             /* used by sdsf     */
"tracks space(100,100) lrecl(133) recfm(f,b,a) dsorg(ps)"
"alloc f(temp1) da('z198.SAMPLE.output1') shr"

/*SAY 'ENTER JOBID:'
  PULL ID
  jobid = strip(ID)

  JOBID = 'JOB02911'

  SAY 'ENTER JOBNAME:'
  PULL JNAME
  JOBNM = STRIP(JNAME) */

RC = ISFCALLS(ON)
ISFPREFIX = "TB796"
ADDRESS SDSF "ISFEXEC ST"
IF RC <> 0 THEN
DO
 SAY 'ERROR'
 EXIT 20
END
LOOP = ISFROWS
DO I = 1 TO LOOP
 COLVAL = VALUE(JOBID.I)
 IF COLVAL = 'JOB07050' THEN
 DO
  ADDRESS SDSF "ISFACT ST TOKEN('"TOKEN.I"') PARM(NP ?)"
  IF RC <> 0 THEN EXIT
  DO J = 1 TO STEPN.0
    IF STEPN.J = 'TSCRATCH' THEN
      IF DDNAME.J = 'SYSIN' THEN
        do

QUEUE "PRE" TB796
queue "st"
/*queue "filter jobid eq "jobid*/
QUEUE "FIND " COLVAL
queue "++?"                                 /* open output of job    */
queue "find" SYSIN
queue "++S"
say ' am after sysin '
queue "print file temp1"                /* print to temp dataset */
queue "print 1 999999"
queue "print close"
queue "end"
queue "exit"
"execio" queued()" diskw isfin (finis"     /* input to sdsf batch   */
address ispexec "select pgm(isfafd) parm('++25,80')"/* invoke sdsf */
  END
  END
 END
END
RC = ISFCALLS(OFF)
