JCL program Copy Book Copylib
You have mentioned the copylib in JCL program but the copy book is not expanded in the program what is the possible error you get?
Nandhakumar Babu
- Aug 20th, 2015
Unless there is no variable from the copybook is used in the program there is no issue, but it would result in return of severe code (12) when a variable in the copybook has been used in your application program.

Actually if you mention the copybook library in JCL it doesnt expand it in output. While compiling the program, there will be a option asking "Do you need to expand copy book".Hope this is what you are asking.

Hamsa

SYSPRINT-to print the utility messages in spool
SYSOUT-identifies the system output datasets,which are in
printed or punched format.Shakuntala Dey
- Sep 25th, 2011
SYSPRINT - when there is message from the utility.Say in ur jcl u have used sort.so all the sort related information will be available in SYSPRINT.
SYSOUT - Its to display the messages which is available in our coding. say display statements of cobol will be displayed in sysout -
Can we concatenate two Datasets having different LRECL? If yes, then how?
dhs01
- Apr 15th, 2009
The largest first rule is one that has not been applicable for awhile. At one time this was necessary because of buffer allocations. This is no longer required.
mainframeguru11
- Jun 10th, 2008
THE RULE FOR CONCATANATION IS 1. LRECL and RECORD FORMAT SHOULD BE SAME2. IF THE BLOCK SIZE IS DIFFERENT THEN LARGEST BLOCK SIZE DATASET SHOULD BE IN THE FIRST DSN NAME3. DATASET MAY RESIDE IN DIFFERENT DEVICE AND VOLUMES.

- Apr 15th, 2009
While this may not be an elegant solution, what I would do is to set up a PROC with a substitution variable. I would then invoke the PROC n times using n EXEC cards with the file override substitution.

Calculate total space allocated for file

kckinney
- Sep 3rd, 2010
The traditional answer is (primary+(secondary*15)) or 10+150=160.This question isn't relevant beyond testing the most basic MVS knowledge. The reason is that products such as SMS, STOP37, et...

Almost correct, VSAM and non-VSAM are important but equally important is whether the allocation is to SMS controlled dasd. Another factor to consider is that allocations can both get more and less tha...
