The method and syntax for symbolic substitution has been clearly documented going back to when I started in this business (OS/MVT R18).
It hasn't changed. The syntax for symbol substitution is identical, whether it is a JCL symbol or a system symbol. RTFM is left as an exercise for the original poster. -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Paul Gilmartin Sent: Monday, July 16, 2018 1:42 PM To: [email protected] Subject: Symbol syntax (was: Using system sysmbols in a procedure) (Can't anyone spell "Symbols" correctly in a subject!?)

I read in the JCL Ref.: Using symbols before fixed code A period is required after a symbol when the code that follows the symbol is fixed and begins with: ... o A left parenthesis, when it is at the start of the designation of a relative generation of a generation data group (GDG) that does not contain a plus or minus sign. ... For example, if &SYSNAME resolves to SY1, type DSNAME=PROD.&SYSNAME.(0) if the desired data set name is PROD.SY1(0). If a plus or minus sign is included, the period is optional: DSNAME=PROD.&SYSNAME.(+0) and DSNAME=PROD.&SYSNAME(+0) are both acceptable. So, I can code: PROD.SY1(0) PROD.&SYSNAME(+0) PROD.&SYSNAME.(0) But not: PROD.&SYSNAME(0) Why not? And what does the prohibited form mean? I hate JCL! --gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected]<mailto:[email protected]> with the message: INFO IBM-MAIN ::DISCLAIMER:: -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
