Autoinstall Control Program Call Interface

The ACP has the following call interface:

ENTRY ai-prog-name USING a-string pointer-1 pointer-2
       pointer-3 pointer-4

where:

ai-prog-name: is the program name entered in the Auto Install Exit field of the SIT.

The remaining parameters are part of DFHCOMMAREA as follows:

01  DFHCOMMAREA
    03 a-string     PIC X(4).
    03 pointer-1    POINTER.        pointing to Net-Info.
    03 pointer-2    POINTER.        pointing to Model-table.
    03 pointer-3    POINTER.        pointing to TCT-Info.
    03 pointer-4    POINTER.        pointing to Term-Info.

where:

a-string: contains x'F0' in the first byte. If the autoinstall exit is to reject the install attempt, the ACP should not alter this value. If the autoinstall exit is to accept the install attempt, the ACP should set a-string to LOW-VALUES.
pointer-n: is defined further in the following sections, pointer-1, pointer-2, pointer-3 and pointer-4.

This data format and those for pointer-1, pointer-2, pointer-3, and pointer-4 are supplied in copybook dfhcwai.cpy.
