Hi,
Any idea on how to get the current system date through JCL ?

Try this, using sort:
Code: Select all
//SYSIN DD *
SORT FIELDS=COPY
OUTREC FIELDS=(5:&DATE1,13:&TIME2)
/*

Thanks Anuj. This seems to work, is there any other way to do the same?

Thanks enrico for the comment.
I have told that we can do it without sort also, and there is a requirement to do it with out sort, so I've asked. I was not aware about it before.

then learn to collect all the requirement before asking for a solution
the sort solution is the simplest available

Hello.
There are a number of system symbols that are available for use in JCL which are documented here:
https://www.ibm.com/docs/en/zos/3.1.0?t ... mic-system
The bulk of these symbols relate to dates and times. If you don't want the complete date/time formats provided, there are enough symbols available for you to roll your own date/time format.

You can try using symbol converter EZACFSM1, as zum13 has indicated. One example is here of using symbol converter:

The symbol converter isn't actually necessary. Since version 2, symbols can be put into in-stream data providing JES2 is told to resolve them via the "SYMBOLS" parameter. For example, the following will copy the date and time symbols to sysout:
Code: Select all
//STEP2 EXEC PGM=ICEGENER
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY
//SYSUT1 DD *,SYMBOLS=EXECSYS
&YYMMDD &HHMMSS
//SYSUT2 DD SYSOUT=*
This can be done with user-defined symbols as well, but some use of the "EXPORT" statement would be required.
The facility to use symbols in JCL statements has been around for rather longer so putting them into program parameters or something like a dataset name will work without the need for an additional program to be involved, for instance:
Code: Select all
//STEP1 EXEC PGM=PROG1,PARM='&YYMMDD'
//INPUT DD DSN=&SYSUID..D&YYMMDD,DISP=SHR

Thanks for the discussion. What is a symbol convertor?

Prior to version 2, JES2 could not be told to substitute symbols into in-stream data so if you did
then the string "&YYMMDD &HHMMSS" is what would appear in the SYSUT1 input.
In order to get around this limitation for TCP/IP, a program called "EZACFSM1" was created which looks for the symbols in the input and does the substitutions. This is the symbol converter (it's actually referred to in the documentation as the "symbol translator utility":
https://www.ibm.com/docs/en/zos/3.1.0?t ... em-symbols).
