TPFDF Restricted Assembler Macros: Reference

This chapter documents Product-Sensitive Programming Interface information.

The macros in this section (with the exception of FMSGS) are TPFDF internal macros used to perform system functions. There is no guarantee that the programming interface to these macros will not change. The use of these macros should be restricted to minimize the effect of any changes.

The FMSGS macro is provided for compatibility with older applications. Use the TPF or ALCS WTOPC macro instead of the FMSGS macro whenever possible.

This chapter contains an alphabetic listing of the TPFDF restricted assembler macros. The description of each macro includes the following information:

Format: Provides a syntax (railroad track) diagram for the macro and a description of each parameter and variable. See How to Read the Syntax Diagrams for more information about syntax diagrams.

Entry Requirements: Lists any special conditions that must be true when you use the macro.

Normal Return: Lists what is returned when the macro has completed processing successfully.

Error Return: Lists what is returned when the macro cannot complete processing successfully.

Programming Considerations: Lists any additional considerations for using the macro, including any restrictions or limitations.

Examples: Provides one or more examples that show you how to code the macro.

Related Macros: Lists where to find information about related macros.
