Functions which must be provided by HFMCRAEX

Z Data Tools uses HFMCRAEX to access a supported library. The exit must provide the following high level functions:

  1. Initialize and terminate the exit.
  2. Validate the library.
  3. Extract a member from the library.
  4. Get member information, or metadata. That is, get the name and other information about members, given a member name or name pattern containing wildcard characters.
  5. Get display information. This provides to Z Data Tools the heading to use on a member selection list ISPF panel for members in the library.

These functions are discussed in more detail in the following sections.
