The first page (1P) indicator is set on by the
RPG IV program
when the program starts running and is set off by the
RPG IV program
after detail time output. The first record will be processed after
detail time output. The 1P indicator can be used to condition heading
or detail records that are to be written at 1P time. Do not use the
1P indicator in any of the following ways:
- To condition output fields that require data from input records;
this is because the input data will not be available.
- To condition total or exception output lines
- In an AND relationship with control level indicators
- As a resulting indicator
- When MAIN or NOMAIN is specified on a control specification
