Chapter 1: Introduction

DtlSpawn is a z/OS batch utility program that simplifies the execution of z/OS Unix shell scripts and programs.

DtlSpawn is a free utility licensed under the Apache 2 license, and is also included as part of the Co:Z Co-Processing Toolkit for z/OS

Features:

DTLSPAWN is a utility that is similar to BPXBATCH, however it offers several improvements:

• Accepts input from a STDIN DD pointing to an MVS dataset or spool file, with trailing white space and 73-80 line numbers trimmed.
• Can accept a list of 'ENVAR=VALUE' settings in the PARM= (prior to the name of the command to run).
• Defaults to running the user's default login shell; doesn't require root access to do so.
• Defaults to spawning the program/shell with _BPX_SHAREAS=MUST, which more reliably causes the shell to run in the same address space.
• Accepts unadorned environment variables via //STDENV and automatically handles cleaning up trailing spaces and line nums in //STDENV DD input.
