Working with build scripts

The build script for the Remote Build feature of z/OS® Extensions is called BCL (Build Control Language). It is similar to z/OS MVS™ JCL in appearance and, for many basic parameters and options, it is identical to MVS JCL.

Note: In previous releases, BCL was called pseudo-JCL.

BCL has its own syntax rules with its own supported statement types, parameters, and options. The rules specified in this topic and its subtopics must be followed. Only statement types, parameters, and options specified in this topic are supported. However, for a given statement, parameter, or option supported by BCL (with an identical syntactic specification in MVS JCL), the semantics of such a statement, parameter, or option are consistent with the corresponding BCL unless otherwise stated.

For information about constructing BCL statements, see the following topics:

For information on the syntax of particular BCL statements, see the following topics:

BCL syntax notations

EXEC statement (//… EXEC …)
CALL statement (//... CALL ...)
DD statement (//… DD …)
