I'm running a QMF REXX proc from a job. This proc reads a dataset and use that value to run a query. The query returns a few columns, col1, col2, col3. The value of col3 corresponds to member in a PDS.
col3 can have values daily, weekly, monthly, quarterly & yearly. Based on the value, I need to look up the PDS and run the update query stored in that member.
I'm not sure how to set the value of col3 in my REXX proc. I think I can look up other post to find the member in PDS.
Thanks |

Hi,
Thanks for a speedy response.
I've a JCL which run a proc using a input file
//JS010 EXEC QCPDQMF,
// SYSTEM=DB2S, DB2 SUBSYSTEM
// IEBGCND=0, DO NOT WRITE TO SYSOUT
// OUTDSP1='MOD',
// OUTDSN='USERID.PRINT' REPORT DSN
//PS010.PARMIN DD DISP=SHR,DSN=DDIN(memname)
//PS010.SYSTSIN DD *
ISPSTART PGM(DSQQMFE) PARM(M=B,S=DSNJ,I=userid.proc)
//*
userid.proc
ADDRESS "TSO" "EXECUTIL TS"
TRACE ?R
ADDRESS "TSO" "EXECIO 1 DISKR PARMIN (FIFO FINIS"
PARSE UPPER PULL KEY .
ADDRESS "QRW" "SET GLOBAL (field="key
ADDRESS "QRW" "RUN QUERY" "username.query"
IF DSQ_RETURN_CODE = DSQ_SEVERE | DSQ_RETURN_CODE = DSQ_FAILURE
THEN EXIT DSQ_RETURN_CODE
the query in the proc returns this data
Col1 Col2 Col3
1234 abcd daily
I want use the vaule of col3 to look up a member with same name in a pds and run the query in that member.
I've tried many ways (with my limited knowledge of rexx) to use (set) the value of col3 in my procc. But I'm not successful.
Thanks |

| I know nothing about QMF REXX. Where exactly are those values returned to (the terminal, a dataset, as variables)? |

Hi kevin,
The values are returned to terminal, we can also save the data as a temp table.
I've gone through QMF manual as well as REXX manual, but cannot find something useful.
please help me.
Thanks |

If the query result is stored in OUTDSN, then your rexx program should read this file and analyse the result.
Also, does it have to be batch QMF? You could run the query from within the rexx. |

Thanks for response.
Yes, I've to run a batch QMF only. I'm linking multiple application. I've a bat file to do this, which FTP's a file (created by another application) to mainframe as a PS. Then the bat file submits this job which executes the proc.
This proc reads the input from the file and pass it to the query.
Based on the result from the query, I need to run a update query stored in a PDS and then FTP the result, which will be used by another application as input.
I can export the result of the query to a OUT DSN, but the data is exported in IXF format, which will include the column declaration along with the data retrieved.
Then I think I've to use the sort within rexx to get the value of col3 available to rexx.
But I'm looking if there is more simpler way to use the value of col3 returned from the query. |

| I think the current suggestion is to get your QMF process to put its output to a file and then to read the file from the rexx. |

From what I found when I was running QMF batch (back in 2003):
In your QCPDQMF procedure, there should be a DD card for DSQPRINT. It may look like this:
| Code: |
| //DSQPRINT DD SYSOUT=*,DCB=(RECFM=FBA,LRECL=133,BLKSIZE=1330) |
You have to override it with a DSN, which may look like this:
| Code: |
| //stepname.DSQPRINT DD DISP=(NEW,PASS),UNIT=SYSDA,SPACE=(TRK,(10,1)),DSN=&&QMFOUT |
Then, in the rexx step, you need only have another DD for the same file:
| Code: |
| //QMFOUT DD DISP=(OLD,DELETE),DSN=&QMFOUT |
The report certainly contains header lines, maybe there is a line with '---------' before the dataline.
Read the file with EXECIO, search for the separator line, then get your data.
Without seeing the job procedure , the QMF procedure and the QMF output, there is a lot of guessing in my reply... |

I had another close look at your 1st post.
No doubt your QCPDQMF procedure has:
| Code: |
| //DSQPRINT DD DISP=SHR,DSN=&OUTDSN |
So, all you need in the rexx step is to have a DD for the same file:
| Code: |
| //QMFOUT DD DISP=SHR,DSN=USERID.PRINT <= your OUTDSN parameter |
The following is still correct:

Thank You All.
I'll try the suggestion.
I think I'll change the queries in the PDS to QMF queries.
It will be easier to build the query name and run it rather then finding the meber in PDS and finding a way to get the query from the the pds member.
Thanks |

Whatever. I just hope you are not as confused as I am now!  |
