The autoinstall control program at INSTALL
On invocation, CICS passes a parameter list to the autoinstall control program by
means of a communication area addressed by DFHEICAP. The communications
area is mapped by a copybook that is supplied in each of the languages supported
by CICS.
The assembler form of the parameter list is as follows:
PGAC_PROGRAM
passes the 8-byte name of the object to be autoinstalled. This is an input-only
field, which your user-replaceable program must not alter.
PGAC_MODULE_TYPE
passes a 1-byte indicator of the type of object to be installed. The equated
values are:
PGAC_TYPE_PROGRAM
A program
PGAC_TYPE_MAPSET
A mapset
PGAC_TYPE_PARTITIONSET
A partitionset.
This is an input-only field, which your user-replaceable program must not alter.
PGAC_MODEL_NAME
allows your control program to specify the 8-byte autoinstall model name to be
used. If you do not set this field, CICS uses the default model name for the type
of object:
DFHPGAPG
For a program
DFHPGAMP
For a mapset
DFHPGAPT
For a partitionset.
PGAC_LANGUAGE
allows your control program to specify, in a 1-byte field, the language of the
program to be autoinstalled. The equated values are:
PGAC_ASSEMBLER
Assembler
PGAC_COBOL
COBOL
PGAC_C370
C
PGAC_LE370
Language Environment
PGAC_PLI
PL/I.
