SYMLIST parameter
Parameter type
Keyword, optional
Purpose
Use the SYMLIST parameter to list the symbols that pass to the
internal reader (INTRDR). The internal reader enables
your job to submit another job for later execution. Ensure that the
symbols are defined when your job is submitted to INTRDR. Symbols
are either JCL symbols that are made available to the job execution
phase using the EXPORT statement, or JES symbols that are dynamically
created using the JES Symbol service (IAZSYMBL). The special asterisk
character (*) indicates that all JCL and JES symbols that meet JCL
requirements are passed to the internal reader.
Note: 
This does not include symbols that are defined by JES (such as the
SYSUID symbol), unless they are explicitly exported by using the EXPORT JCL statement.
