Posted: Mon Jun 26, 2023 9:42 am Post subject: Use of multiple copybooks to view a file in File manager
Let's start off by asking whether what I'm trying to do can be done at all.
Assume I have a file that contains 2 record layouts, one for copybook FRED and one for copybook BERT (these are in a PDS called COPY.COBOL).
The program that creates this file is called JOHN.
I would like to create a template (?) in FM that is called JOHN and that "realizes" that if the layout is of type FRED (based on a value in a "FRED" field), then show the record using a copybook definition defined in COPY.COBOL(FRED) , and if it is of type BERT, show using COPY.COBOL(BERT).
Obviously (?), I want to be able to scroll through the file and FM "selects" the correct layout based on the record layout.
I have read through the online manuals but am getting nowhere.
For example, I'm assuming that I can define a template called JOHN, and if I browse this member, I'll see one reference to FRED, and one to BERT. Trouble is, all I ever see is either one or the other, never both at the same time.
At one time (years ago), I had access to in-house documentation which my memory says explained how to do this, but I no longer have access to this.
Grateful for any suggestions. _________________ Michael

misi01,
Sigh ! You have member for more than 20 years and yet you simply cannot follow rules. One of the golden rule to start a new topic is
"Use meaningful topics (don't use the language/forum name/PGM name for the topic). Use a descriptive Title to explain your problem. "
A topic with title "File manager" does NOT help as to what the question is. A better title would be "how to use multiple copybooks to view/edit a file in File manager"

Thank you for that. Worked a treat and passed what I call the "idiot test" (ie, read/follow the instructions to the letter and it works).
I have to say though, I'd already read the link you posted to the IBM manual more than once. That link and the instructions above that you posted were as similar as chalk and cheese. Not sure I'd ever have managed to figure it out from the online manuals.
I'll see if I can put together a word document that explains how you would do the same thing in IDz (though my immediate guess is that you have to ceate the XREF file in FMM under TSO first, but we shall see. I'll post it you when I'm done.
Thanks again. _________________ Michael

Thought I'd add this as "extra" documentation (though Peter's is very good).
I originally had a condition for a specific layout being chosen as the following
Quote:
Ä3 = 'WW-CREATE-TFT950' ! Ä3 = 'WX-DELETE-TFT950'
which would obviously result in a massively long string for multiple string text comparisons.
After reading the online help about the use of Rexx in conditions, I experimented my way to this (though this isn't really using Rexx)
Quote:
AND COPYNAME CO 'TFT950'
which resulted in the following condition
Code:
1 Id : TFLD('Ä3','CO','TFT950') +
2 Sel: +
Offset 0 CCSID
Cmd Seq SHE Ref Field Name Picture Type Start Length
**** Top of data ****
1 1 TFT950-GROUP AN 1 172
2 2 ORGNR 9(12) ZD 1 12
3 2 COPYNAME X(30) AN 13 30
4 2 TFT950 AN 43 130
Originally, I'd thought to use the Rexx POS fuction, but I couldn't figure out to phrase it via option 1. Whatever variation I tried, I received an error message.
The online help includes an example
Quote:
For example, if you want to select records in which characters 4-6 of field
Ä22 are the string 'NOT', you could specify:
SUBSTR(Ä22,4,3) = 'NOT'
but it doesn't show how to enter this via option 1. Where does the SUBSTR text go, where do 4 and 3 go, where does 'NOT' go? _________________ Michael

Misi01,
If the panels don't show the option of entering a substring, why not improvise( following Keep it SIMPLE) and split the long field name into a individual fields that you want to add a condition?

Unfortunately, the problem with that idea is that it can't (?) work.
The actual field names could vary quite a lot and are based on COBOL section names.
This means that in one scenario, it might be W-FETCHNEXT-TFT950 and in another WA-ISRT-TFT950 (the TFT950 will always be the same, but not where it is in the actual string).
That's why being able to use the POS function would have been good (okay, fortunately I can use the CO variation in this scenario)
But then comes the problem of how I enter the actual Rexx string in the FMM panel (which values go where) _________________ Michael

misi01,
Sigh ! you seem fixated on one solution of REXX string and you never seem to look beyond it.
If it is dynamic COBOL section names, why not define the concerned field in the copybook as an array of 1 byte and occurs for "n" times where "n" is the full length. And then fill in the value as you need. _________________ Kolusu - DFSORT Development Team (IBM)

You know what?
I think I'll simply submit the problem as a documentation error to IBM and let them waste time and money on fixing it/documenting it properly.
The online help clearly states that you can use a rexx function to select specific records, but gives no example of how to do it.
Your suggestion is for me to jump through all sorts of hoops to circumvent an IBM problem. The next person might not be able to use those hoops at all and NEEDS the rexx solution. _________________ Michael

After a telephone meeting with IBM, the answer as to how to use Rexx for selection was as follows:
Rather than using option 1
Code:
----------- Criteria - Enter 1 or 2 to specify expression by field -----------
1 Id : TFLD('Ä3','CO','TFT950') <------- my original attempt +
2 Sel: +
Offset 0 CCSID
Cmd Seq SHE Ref Field Name Picture Type Start Length
**** Top of data ****
1 1 TFT950-GROUP AN 1 172
2 2 ORGNR 9(12) ZD 1 12
3 2 COPYNAME X(30) AN 13 30
4 2 TFT950 AN 43 130
try the following instead
Code:
----------- Criteria - Enter 1 or 2 to specify expression by field -----------
1 Id : +
2 Sel: pos('TFT950', Ä3) > 0 <----- any (?) Rexx statement(s) that produce 0 or 1 +
Offset 0 CCSID
Cmd Seq SHE Ref Field Name Picture Type Start Length
**** Top of data ****
1 1 TFT950-GROUP AN 1 172
2 2 ORGNR 9(12) ZD 1 12
3 2 COPYNAME X(30) AN 13 30
4 2 TFT950 AN 43 130
There you have it. Simple (when you know how) _________________ Michael
