IBM S544-5285-01 Record Bytes, Reserved1 Bytes, Recordln Bytes, Reserved2 Bytes, Request Byte

record (Bytes 9–12)

A pointer to the first byte of the input record including the c character. The record resides in a buffer that resides in sto ACIF, but the exit program is allowed to modify the input record

reserved1 (Bytes 13–16)

These bytes are reserved for future use.

recordln (Bytes 17–18)

Specifies the number of bytes (length) of the input record. If modified, this parameter must also be updated to reflect the a record.

reserved2 (Bytes 19–20)

These bytes are reserved for future use.

request (Byte 21)

Specifies how the record is to be processed by ACIF. On entry program, this parameter'00 '.is WhenX the exit program returns control to ACIF, this parameter must have the'00 ', value'X01', Xor'02X', where:

X '00	'	Specifies that the record be processed						by ACIF.
X '01'		Specifies	that	the	record	not	be processed		by	ACIF.
X '02	'	Specifies	that	the	record	be	processed	by	ACIF	and contr

program can set			this	value	to save the current record, ins
