SYMLIST parameter

Parameter type: Keyword on EXPORT statement, required

Purpose: Use the SYMLIST parameter to list the JCL symbolic parameters to be exported, and therefore, made available to the job step program. Symbolic parameters can be set to values in the JCL with the SET statement or through PROC symbolic parameter processing. Exported symbolic parameters must be set to a value at a point in time in the job stream after the EXPORT command, and prior to the execution of the job step program. Symbolic parameters can be set to values in the JCL with the SET statement or through PROC symbolic parameter processing. Exported symbolic parameter values can also be passed into in-stream (sysin) data; see Using symbols in JES in-stream data for details.

Exported symbolic parameters must be set to a value in the job stream after the EXPORT statement. Exported symbol values are resolved to the last value set prior to or within the current job step. JCL Converter processing generates EXPORT EXPSET statements to manage how exported JCL symbol values are resolved. These statements appear in the job log. Reviewing the placement of EXPORT EXPSET statements in the job log might be helpful in understanding exported symbol resolution for a given job.
