Calling the ASASYMBM service

A call to ASASYMBM:
  1. Defines, to the system, the system symbols that ASASYMBM is to use.
  2. Defines, to the system, user symbols that are specified in the symbol table (as described later).
  3. Substitutes values for the symbols in the symbol table, based on an input character string (pattern).
  4. Places the results of the substitution in an output buffer that the caller specifies.
  5. Places the length of the output buffer in a field.
  6. Provides a return code to the calling program.

You must include the ASASYMBP mapping macro to build the user parameter area (SYMBP) for ASASYMBM. The information describes how to set up ASASYMBP to enable the desired functions.
