Hi
I have a JCL which gives me following output..
Code:
 ----+----1----+----2----+----3----+----4----+----5----+----6----+----7--
 ***************************** Top of Data ******************************
                  CONTENTS OF VTOC ON VOL AAR001  <THIS VOLUME IS NOT SMS
 - THERE ARE   599 EMPTY CYLINDERS PLUS   137  EMPTY TRACKS ON THIS VOLUM
                  CONTENTS OF VTOC ON VOL AAR002  <THIS VOLUME IS NOT SMS
   THERE ARE   559 EMPTY CYLINDERS PLUS   691  EMPTY TRACKS ON THIS VOLUM
                  CONTENTS OF VTOC ON VOL AAR003  <THIS VOLUME IS NOT SMS
   THERE ARE   969 EMPTY CYLINDERS PLUS   106  EMPTY TRACKS ON THIS VOLUM
                  CONTENTS OF VTOC ON VOL AAR004  <THIS VOLUME IS NOT SMS
   THERE ARE   856 EMPTY CYLINDERS PLUS    41  EMPTY TRACKS ON THIS VOLUM
                  CONTENTS OF VTOC ON VOL AAR005  <THIS VOLUME IS NOT SMS
   THERE ARE  1194 EMPTY CYLINDERS PLUS   145  EMPTY TRACKS ON THIS VOLUM
                  CONTENTS OF VTOC ON VOL AAR006  <THIS VOLUME IS NOT SMS
   THERE ARE  2284 EMPTY CYLINDERS PLUS    23  EMPTY TRACKS ON THIS VOLUM


What I need to do is...I need a Rexx which multiplies Empty Cylinders with 15 and add it to Empty Tracks to get the total Free Tracks..for each volume.....and compares all the free Tracks and find which volume has tracks less than 3800... Can someone please help me with the REXX code...

Thanks

I am more than willing to HELP people with code problems, but certainly not to supply custom code for them, unless paid to do so.

My current rate would be around 500 euro for the task above icon_biggrin.gif

This is an excellent opportunity for you to sit down with the REXX manual and try a few things out, and to start learning the language. Then is the time to post on the forum for help rather than code.

Good luck.

Doing calculations in REXX are as easy as writing an equation.

Code:

CTRO1 = 0
CTRO1 = CTRO1 + 1


The value of CTRO1 is now 1.

Code:

CYLS = 50
TRKS = CYLS * 15


The value of TRKS is now 750.

Code:

TRKS = 1500
CYLS = TRKS/15


The value of CYLS is 100.

They can also be complex.

Code:

CYL1 = 100
CYL2 = 200
CYL3 = 300
TRKS = (CYL1 + CYL2 + CYL3)*15
 


The value of TRKS is 9000

icon_smile.gif Thanks Cpuhawg.... If I would know the code ...I would be able to do the multiplication and division....but unluckily...I don't know how to write the code in Rexx..... Expat wants 500 Euros.... hahahahaha for this task...well I am still waiting for someone or him to help me with the code....or give me a sample code to solve my problem.......may be he might give the code free to me..... hahahahaahahaha........

1. Your existing JCL needs to be changed to put the report into a file that can be accessed later.

2. You need an additional step that has a DD with a referback to previous report.

3. that new step is PGM=IKJEFT01 and calls your new rexx routine

4. rexx routine needs to read the report and process 1 record at a time, doing the required math.

Please send 495 Euros to me for consultation.

Hello,

Not knowing rexx should not prevent getting an answer.

If you are a programmer, you can use any language (cobol, easytrieve, etc), to read the data you posted and do the calculation.

If you need this in a hurry, you have alternatives.

no, it means the important part is telling how to do; the actual doing of it is fairly simple and left to the user. icon_cool.gif

Well I didn't do much... Read the File with
"ALLOC DA('DATASET NAME') F(INPUT) SHR"
"EXECIO * DISKRU INPUT (STEM LINE."
using loop read the line one by one...till LINE.0 and then used SUBSTR to get what I want from the line..and did some calculation on that.....
Thanks to all...now I can start with learning REXX... icon_smile.gif
