CIA-MAP-HEADER header structure

When the server runtime processing is running in passthrough mode, the CIA-MAP-HEADER structure is required. It must immediately follow the CIA-SCREEN-HEADER structure. To view the passthrough map header, see copybook DFHMALMH in the SCIZMAC library.

The following table highlights field information within the passthrough map header structure CIA-MAP-HEADER.

A field's type can be one of the following:
  • X - the field contains characters.
  • 9 - the field is a numeric.
  • FB - the field is a fullword binary.
