How to check whether a particular member is present in a PDS.
I checked in the forum and I got that we need to check return value of SYSDSN(pdsname(member)) for the answer.
But SYSDSN() give the return value "DATASET NOT FOUND" for all the members irrespective of their presence.
(note : SYSDSN(pdsname) works well to find whether the PDS is catalogued or not ) |

Hmm. Works for me.
| Code: |
/* REXX */
retcode = SYSDSN('''MY.PDS(MEMBER1)''')
Say retcode
retcode = SYSDSN('''MY.PDS(MEMBER2)''')
Say retcode
|
If only MEMBER1 is in the PDS, I get
OK
MEMBER NOT FOUND |

Using ISPF Library Management (LM) Services also works well.
| Code: |
/* REXX */
"ISPEXEC LMINIT DATAID(did) DATASET('MY.PDS') ENQ(SHR)"
"ISPEXEC LMOPEN DATAID("did") OPTION(INPUT)"
"ISPEXEC LMMFIND DATAID("did") MEMBER(MEMBER1) STATS(YES)"
Say rc
"ISPEXEC LMMFIND DATAID("did") MEMBER(MEMBER2) STATS(YES)"
Say rc
"ISPEXEC LMCLOSE DATAID("did")"
|
If only MEMBER1 is in the PDS, I get
0

Regarding a previous example:
| Code: |
/* REXX */
retcode = SYSDSN('''MY.PDS(MEMBER1)''') |
The use of multiple single quotes is a source of confusion for some. I like using double quotes to define the constant and then use single quotes within, such as:
| Code: |
/* REXX */
retcode = SYSDSN("'MY.PDS(MEMBER1)'") |
