TIRHELPX—Help Interface Exit

TIRHELPX is a runtime exit containing code for the flow to the application Help business system. TIRHELPX is written in COBOL. The same sample exit is included in various z/OS Runtime DLLs, each used by the specific target environment.

Sample code is included as comments. Until modified, TIRHELPX displays the message:

No help available.

If the TIRHELPX sample code is used (by removing the comment characters), the following occurs:

  1. TIRHELPX checks the flags and determines which procedure in the application help business system (field description, screen description, or permitted values) to flow to.
  2. TIRHELPX then calls TIRMSG, which performs the transfer to the target procedure.
  3. After the help procedures have completed and the exit is entered, a SET NEXTTRAN TO CONCAT(TRIM(input tirhelp trancode) is performed to return to the calling application.
