JCL for BCDIN configurations options

Use the //BCDIN JCL statement to control the z/OS Batch Runtime configuration options. Some support elements obtain their options from Java™ system properties.

When creating a configuration options file, the following rules apply:

Options must appear in the keyword=value format
Options must be coded in columns 1 through 71 of the record. Long options can be continued by coding a non-blank character in column 72 and continuing on the next line.
Comment lines contain a # in column one.
Blank lines are ignored.
Options are case sensitive.
When you specify an option more than once, the last occurrence is used.
