INDEXSTARTBY

Specifies the output page number by which ACIF must find a group indexing field, if ACIF is indexing the file.

Note: GROUP, RECORDRANGE, and FLOAT triggers apply only if you are using enhanced indexing. A group indexing field is based on a GROUP or RECORDRANGE trigger, not on a FLOAT trigger.
INDEXSTARTBY={1 | nn}
The values are:
1
Specifies that ACIF must find a group index on the first page.
nn
Specifies the output page number (0 - 99) by which ACIF must find the group index criteria specified. 0 indicates that there is no limit to the page where ACIF must find a group indexing field.

This parameter is helpful if, for example, your file contains header pages. If your file contains two header pages, you can specify a page number that is one greater than the number of header pages (INDEXSTARTBY=3).

If ACIF does not find a group indexing field before the page number specified in the INDEXSTARTBY parameter, it issues a message and stops processing. If you do not want ACIF to stop processing when it cannot find a group indexing field or when a file is empty, you must set the parameter to INDEXSTARTBY=0 or specify EXTENSIONS=EMPTYOK.
