IBM S544-5285-01 manual Inserted eof whenis

work (Bytes 1–4)

A pointer to a static, 16-byte memory block. The exit program can parameter to save information across calls (for example, pointers t areas). The 16-byte work area is aligned on a full word boundary

initialized			to	binary	zeros prior to the first call. The user-wri
must	provide		the code		required	to manage	this	work area.
pfattr (Bytes		5–8)
A pointer to the print					file attribute data structure. See				“Attrib
Print	File”		on	page 74	for more	information	on the	format of	this
and	the	information contained in				it.

record (Bytes 9–12)

A pointer to the first byte of the output record. The record (where KB equals 1024 bytes) buffer. The buffer resides in st ACIF, but the exit program is allowed to modify the output recor

recordln (Bytes 13–14)

Specifies the length, in bytes, of the output record. If the modified, this parameter must also be updated to reflect the a record.

request (Byte 15)

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 ' valueor'01X',X where:

X '00 '	Specifies	that	the	record	be	processed	by ACIF.
X '01'	Specifies	that	the	record	be	ignored by	ACIF.

A value of'00 'X on entry to the exit program specifies that the r processed. If you want to ignore the record,request bytechangevaluetheto X'01'. Any value greater'01than' is Xinterpreted'00 ';astheX exit processes the record.

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

eof (Byte	16)
An End-Of-File eof( ) indicator. This indicator is a 1-byte							character
signals		when	ACIF	has finished writing the output		file.
When eof is signaledeof value=‘Y’),( the last record has already been
presented to the output					exit.recordThe ispoinoterlonger	valid.	Records
may	not	be	inserted eof whenis		signaled. The following	are the only vali
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 ex return to ACIF. The exit program cannot change this parameter.
