About Built-In Functions

CA ADS built-in function support enables an installation to change the invocation names of built-in functions and to generate user-defined built-in functions. This appendix discusses the following topics:

• The internal structure of built-in functions
• The assembler macros that define components of built-in functions
• How to change invocation names
• How to create user-defined built-in functions

To change invocation names, the user needs only to read the following topics:

• The discussion of the master function table under 'Internal Structure of Built-in Functions'
• The discussion of the #EFUNMST macro under 'Assembler Macros'
• The instructions provided under 'Changing Invocation Names'
