Hi friends,
I am working on a REXX code to delete a member in pds with members starting with 'PA'. The below is the code
| Code: |
ADDRESS ISPEXEC
"LMINIT DATASET('"INDS"') DATAID("DATA1") ENQ(EXCLU)"
SAY RC
IF RC = 0 THEN DO
"LMOPEN DATAID("DATA1") OPTION(OUTPUT)"
END
IF RC = 0 THEN DO
"LMMDEL DATAID("DATA1") MEMBER('"PA"')"
END
"LMCLOSE DATAID("DATA1")"
"LMFREE DATAID("DATA1")"
|
Here INDS I am pulling from an ISPF panel I had created.
The issue I am facing is that the LMOPEN is not identifying the dataid created by LMINIT. Instead its picking some IDs like this : ISR00017, ISR00014 and the same by LMMDEL too. So, its not deleting the members I intended to.
Please find below the messages I am getting in trace:
| Code: |
ADDRESS ISPEXEC
"LMINIT DATASET('"INDS"') DATAID("DATA1") ENQ(EXCLU)"
"LMINIT DATASET('"
"INSRI01.TEST11.PROCLIB"
"LMINIT DATASET('INSRI01.TEST11.PROCLIB"
"') DATAID("
"LMINIT DATASET('INSRI01.TEST11.PROCLIB') DATAID("
"DATA1"
"LMINIT DATASET('INSRI01.TEST11.PROCLIB') DATAID(DATA1"
") ENQ(EXCLU)"
"LMINIT DATASET('INSRI01.TEST11.PROCLIB') DATAID(DATA1) ENQ(EXCLU
"LMOPEN DATAID(ISR00017"
") OPTION(OUTPUT)"
"LMOPEN DATAID(ISR00017) OPTION(OUTPUT)"
"LMMDEL DATAID("DATA1") MEMBER('"PA"')"
"LMMDEL DATAID("
"ISR00017"
"LMMDEL DATAID(ISR00017"
") MEMBER('"
"LMMDEL DATAID(ISR00017) MEMBER('"
"LLB"
"LMMDEL DATAID(ISR00017) MEMBER('LLB"
"')"
"LMMDEL DATAID(ISR00017) MEMBER('LLB')"
RC(8) +++
|
By any chance any one of you came across this situation ? Kindly help.
Warm regards

| RC(8) is "The member was not found". Perhaps you should be looking there for the problem. |

Hi Superk,
Thanks for the reply. I double checked the input dataset for the members starting with 'LLB' as in the code. Many members are present.
My doubt is whether the LMINIT is correctly associating the input dataset with the dataid specified and the LMMDEL is searching for the correct dataset to delete the members.
I will once again check in the direction you showed.
Regards
Srikant |

PA in the LMMDEL is the pattern I am pulling from the ISPF panel..
| Code: |
ssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss
********************DELETE PDS MEMBERS MATCHING PATTERN********************

Your last comment is just useless, it is clear what the PA stands for
looks like
You did care to use the MODEL facility
or read the ISPF manual here
publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/Shelves/ISPZPM70
not the latest one, more than enough for the task

| I found the issue. Problem with the LMMDEL utility is that it can delete the member from a PDS only if the complete name is specified. It cant delete all the PDS members that are starting with the given pattern(as I did in my REXX code). That is the reason why it is giving RC 8 saying member not found. |

| Well , thats the conclusion I came to after testing the program with hard coded values. Try out yourself. |

completely clueless aren' t You !
with my first reply with the LMMDEL statement in large font
I hoped to make You notice that the statement as written is just plain wrong
not as You wrote it
"LMMDEL DATAID("DATA1") MEMBER('"PA"')"
but it should be
"LMMDEL DATAID("DATA1") MEMBER("PA")"
the way You wrote it does not give any <syntax> error, it just issues a return code 8 for member not found
and as far as
| Quote: |
| LMOPEN DATAID giving dataid as "ISR00014" |
the dataid is just an ISPF internal <handle> to the dataset being processed
and since Your profile says Mainframe Skills: Pure Mainframe; nothing else!
I should have expected Your discomfort in reading the manual where it clearly states
| Quote: |
2.36.3 Parameters
data-id
The data ID associated with the data set from which a member is to be deleted. The data ID has been generated by the LMINIT service. The maximum length of this parameter is 8 characters.
member-name
The member name or pattern of the members to be deleted. An asterisk (*) indicates that all members are to be deleted. The maximum length of this parameter is 8 characters.
Where member-name is the name of a primary member, the primary name and all associated alias names are deleted. Where member-name is an alias member, only the alias name and its directory entry are deleted.
Where a member pattern has been specified for the LMMDEL service, these rules apply:
All primary members whose name matches the member pattern are deleted.
All aliases that are associated with a primary member whose name matches the member pattern are deleted, even if the alias name itself does not match the member pattern.
All aliases whose name matches the member pattern are deleted, even if the alias is associated with a primary member whose name does not match the member pattern.

I had modified the code and tested it after your first reply. I got what you intended. But unsure of the reason why the code is not picking the pattern.
I had read through the manual many times over before posting my conclusion. I think you are right that my testing is incomplete. Need to check more. |

there is one thing weird ( I' ll investigate as soon as I have a bit of time )
the message about member not found is issued by the LMMDEL service itself
and the return code is still 0 |

Enrico, thanks a ton for taking time to write the program and test it. I will check from my side what I am missing in my code.

lmmdel, and probably other services dealing with <members>/<patterns>
<member> not found behavior
if the <pattern> is not found ISPF sets the message and RC = 0
if the <member> is not found ISPF does not set the message and RC = 8
to investigate further and check the ISPF apar status |

I think this is wrong:
| Code: |
| "LMINIT DATASET('"INDS"') DATAID("DATA1") ENQ(EXCLU)" |
The dataid in LMINIT should be the name of the variable. Other services will use the value of the variable. It works in this instance, but would not work correctly if it was in a loop.
It works because the value of an uninitialized variable is itself (but uppercase). |
