IBM S544-5285-01 manual Output Record Exit

RECORD@	(Bytes 9–12)
A	pointer to the first byte of the index record, including the c
character.			The record resides in a 32KB buffer (where KB equals
The		buffer	resides	in storage allocated by ACIF, but the exit pr
to		modify	the index	record.

RECORDLN (Bytes 13–14)

Specifies the length, in bytes, of the index record. If the ind modified, this parameter must also be updated to reflect the act record.

REQUEST (Byte 15)

Specifies how the record is to be processed by ACIF. On entry t program, this parameter'00 '.is WhenX the exit program returns control to ACIF, this parameter must have the'00 ' valueor'01X',X where:

X '00 ' Specifies that the record be processed by ACIF.

X '01' Specifies that the record not be processed by ACIF.

A value of'00 'X on entry to the exit program specifies that the rec

processed. If you want to ignore the record,REQUEST changebyte valuthe to 'X01'. Any value greater'01than' is Xinterpreted'00 ',asandX the exit processes the record.

Note: Only one record can reside in the buffer at any time.

EOF (Byte 16)

Specifies an end-of-file (EOF) indicator. This indicator is a 1-byte code that signals when ACIF has finished processing the index objec

When EOF is signalled (EOF value = “Y”), the last record has alread presented to the index exit. The pointer RECORD@ is no longer valid. Records cannot be inserted when EOF is signalled. The following are valid values for this parameter:

Y Specifies that the last record has been written.

NSpecifies that the last record has not been written.

This end-of-file flag, used as a last call indicator, allows the exi return control to ACIF. The exit program cannot change this parameter

Output Record Exit

The	exit	receives	control	before a		record	(structured		field)	is wri

Figure 32 on page 127 contains a sample DSECT that describes the control passed to the exit program.
