What is Sysproc in mainframe?

SYSPROC is a system file that originally contained only CLISTs written for applications or for an individual’s use. You can issue the EXECUTIL SEARCHDD(NO) command directly from the terminal, from an exec or CLIST, and from the JCL input stream run in TSO/E background. The ALTLIB command can also affect search order.

What is unique concerning REXX execs?

However, a significant difference between REXX execs and CLISTs is that you can execute CLISTs only in a TSO/E environment. REXX execs do not require a TSO/E environment, and can execute in any MVS™ address space. You can also write APPC/MVS transaction programs in the REXX language.

What is a Sysproc?

SYSPROC is a system file that originally contained only CLISTs written for applications or for an individual’s use. SYSPROC now can also contain execs as long as the execs are distinguishable from CLISTs. The SYSEXEC file is searched first, followed by SYSPROC.

Does Rexx support recursive function?

Recursive Functions Any recursive function could be coded in a traditional non-recursive fashion (or iteratively), but sometimes recursion offers a better problem solution. Not all programming languages support recursion; Rexx does.
