General programming services

This information provides an alphabetic listing of the z/TPF general programming services, also referred to as general macros. General macros are used by z/TPF application programs that need system programming services. No special authorization is required by the general macros, although some parameters might be restricted, as noted.

The description of each general macro includes the following information:
  • A brief description of what you use the macro for.
  • Last updated: Provides historical information about when the general macro was added, changed, obsoleted, or replaced.
  • Format: Provides a syntax (railroad track) diagram for the general macro and a description of each parameter and variable.
  • Entry requirements: Lists any special conditions that must be true on entry to the general macro.
  • Return conditions: Lists what is returned when the general macro finishes processing.
  • Programming considerations: Lists any additional considerations for using the general macro, including any restrictions or limitations.
  • Examples: Provides one or more examples that show you how to code the general macro.
