DD statement. The result of such an occurrence is that ACIF will terminate
abnormally.

INDEXDD=INDEX |
filename (DEVT
=
TAPE | DISK) (VSE)
Specifies the file name that appears on the DLBL or TLBL JCL statement, a
1–7 character string containing only those alphanumeric characters supported
in the operating environment. The following are the characteristics for the file:
Ÿ
A block size of 32 760
If a record length other than 32756 is specified, it is possible that ACIF will
produce a record of length greater than that which is allowed by the DLBL
or TLBL JCL statement. The result of such an occurrence is that ACIF will
terminate abnormally.
Ÿ
A maximum record length of 32 756

Assigned to programmer logical unit 009
INDEXOBJ=GROUP | ALL | NONE
Specifies the amount of information ACIF puts in the index object file.
Selecting GROUP causes only group-level entries to be put in the index object
file, which saves space. Selecting ALL causes both page-level and group-level
entries to be put in the index object file. You should select ALL if you are
indexing a file for use with the Viewer application of AFP Workbench. If this
parameter is not specified, ACIF uses GROUP as the default. Choose NONE if
you do not require an external index file. Choosing NONE will also reduce ACIF
storage requirements.
INDEXSTARTBY=1| nn
Specifies the output page number by which ACIF must find an indexing field, if
ACIF is indexing the file. If ACIF does not find an indexing field, it issues a
message and stops processing.
This parameter is helpful if your file contains header pages. You can specify a
page number 1 greater than the number of header pages, so that ACIF will
continue to look for matches for the number of pages specified for this
parameter.
INDXEXIT=
module name
Specifies the name of the index record exit program. This is a 1–8 byte
character name of the load module ACIF loads during initialization and
subsequently calls for every record (structured field) it writes to the index object
file (INDEXDD). If this parameter is not specified, no index record exit is used.
See “Index Record Exit” on page 69 for more detailed information.
INPEXIT= module name
Specifies the name of the input record exit program. This is a 1–8 byte
character name of the load module ACIF loads during initialization and
subsequently call for every input record it reads from the input file (INPUTDD).
If this parameter is not specified, no input record exit is used. See “Input
Record Exit” on page 123 for more detailed information.
