Good morning everyone,
I have a problem I can not extrapolate GDG of some files, I would find the last level and date of creation, the last level I can find it, but the creation data can not, please indicate where I wrong?
If the REXX launch date of creation is always EXTENDED:
| Code: |
GDG = E16.S04.CRIFFER.A03300RA.GDG
DSN = E16.S04.CRIFFER.A03300RA.GDG.G0002V00
CREATION = EXTENDED |
| Code: |
/* REXX */
GDG=E16.S04.CRIFFER.A03300RA.GDG
X = OUTTRAP(LST.) /* LISTCAT GDG BASE */
" LISTC ENT('"GDG"') ALL"
X = OUTTRAP(OFF)
SAY 'LST.0 IS =' LST.0
/* FIRST FIND = 0 GDG */
DO I = LST.0 TO 1 BY -1
IF POS('NONVSAM',LST.I,1) > 0 THEN
DO
DSN = SUBSTR(LST.I,POS('NONVSAM',LST.I)+13,44)
SAY 'LST.I=' LST.I
I = 0
END
END
DO Z = LST.0 TO 1 BY -1
IF POS('CREATION',LST.Z,1) ^= ' ' THEN
DO
DTCREAZ = SUBSTR(LST.Z,POS('CREATION',LST.Z)+1,100)
SAY 'LST.Z=' LST.Z
Z = 0
END
END
SAY "----------------------------------------------"
SAY "GDG =" GDG
SAY "DSN =" DSN
SAY "CREATION =" DTCREAZ
ADDRESS ISPEXEC
DSNLEV = 'STS58.SUN.LISTC'
"LMDINIT LISTID("LSTID") LEVEL("DSNLEV")"
"LMDLIST LISTID("LSTID") OPTION(LIST) DATASET(DSVAR) STATS(YES)"
"LMDFREE LISTID("LSTID")"
|
Many thanks. |

| Also, presumably these are disk datasets. I'm pretty sure it's been discussed many times here that you can't get this information for tape datasets. |

| Can't recall exactly, but I do believe that using CSI you should get the data. |

When I do a
| Quote: |
| listc ent(dsn) all |
I get a creation date - these are gdgs on dasd but that may be irrelevant as I presume LISTC is looking at the catalog and not the datasets. |

| Can you post the output of the LISTC command? (I never use GDGs !) |

What are you trying to do by checking result of POS for that value?
Is Z=0 to get you out of the loop? Ugly, and I don't know what it would do. What's wrong with "leave Z"? |

Ghellar, you'd have had your answer at 2:03pm if you'd done this. Or did you already find it and not "fess up" so we continued wasting time on it?
When you looked at your results, dindn't you wonder where "EXTENDED" came from? Didn't you listcat the dataset and try to find "EXTENDED". And notice that the leading spaces (unlike your other two outputs, which don't have them) match up with the number of spaces on your output?
Your code would benefit from more work. Error checking. Correct premature exit from the loops (you've been here six years, I can't believe you are messing with loop counters inside the loop). Neater method for the multiple POS's. Etc. Quite a lot more work.
If you ask a question here, provide answers when people request more information. If you spot the problem yourself, tell us, so we can stop looking. If you think that the error made you look a fool, so you didn't want to, and you'd avoid that - think again.
With rexx, use trace. You'd not even have bothered asking us, you'd know.
Enough.
Just for fun, search the DFSORT forum and find an example that might allow you to junk yours. |

Good morning everyone and thank you for your answers, sorry but I am out of office work these days and I can connect for a short time.
Excuse me if I'm no expert of REXX is the first time in a long time that I write for a problem, I can usually resolve on its own.
The files are on disk, or migrated to tape, you can not call them back to disk, because I have a lot of files to analyze.
As you can see in row No. 4 is the date: CREATION -------- 2005,095
But I can not capture it.
Result of the command LISTC ENT(E16.S04.CRIFFER.A03300RA.GDG) ALL:

Here is the "date" you are extracting.
Did you read my posts? If I was too rude, try enrico's.
You have a test on the result of POS which will always be true. Therefore, the first line that you give it will always give a match, whether or not your search string exists in that line. So, since the first line you give it is the last line, it will always use the last line. Since your search string does not exist, the result of the POS will be zero, and that is where you will take your date from. Since you have conveniently allowed for 100 characters for the date, you pick up the word "EXTENDED" as well. |
