Writing a customizing macro definition

Attention: This topic contains Product-sensitive Programming Interface and Associated Guidance Information.
You have to supply a complete assembler macro definition that is invoked by CICS-supplied assembler macros. The definition of a customizing macro must be written according to the rules for assembler macro definitions. The macro invocations in the definition must also follow the rules for assembler language macro statements. A customizing macro definition contains the following elements:
  1. A MACRO statement to begin the definition.
  2. The name of the macro.
  3. Any number of invocations of the DFHMDX macro.

    The syntax of DFHMDX is described in The DFHMDX macro, and its use is described in Customization examples. DFHMDX is invoked from within DFHMSX.

  4. A MEND statement to end the definition.
