Specifies the maximum number of pages that ACIF can put into a group.

The value is:
A 1- to 4-digit number (1 - 9999).

If the maximum number of pages is reached before a group index value is changed, ACIF forces a new group. If you do not specify GROUPMAXPAGES, ACIF does not end the current group and begin a new group until the value of one of the fields that is specified with the BREAK=YES option on the INDEX parameter changes.
