Ÿ For VSE files, additional file transfer parameters are available.

Ÿ For files with machine carriage control, you can specify BINARY,

CC.This provides an EBCDIC file with correct carriage controls sep

ASCII newlines and carriage returns. You must, however, “trick” ACI
a prefix'0320202020200AofX	'.

FTP

From most

systems,

works

similarly

to

file

transfer,

and most

of

options

are

provided.

Also,

when

executing

FTP

on an

AIX

system,

you

the extraneous carriage return. However, you must test and check y

implementation;

some

FTPs

use

IMAGE

as

a

synonym

for

BINARY.

Other Considerations for Transferring Files to

AIX

Conventional file transfer programs cannot correctly handle the combinati

variable-length files, which contain bytes that cannot

be

translated

f

original representation to ASCII, and may

also

contain

machine

control

c

mixed line data and structured fields,

or

special code

points

that

mapping 4.

Your

best

solution

is to either NFS-mount the

file,

or

write

program on

the

host

system

that appends the 2-byte

record

length

to

and transfer the file binary.

Generally, NFS-mounted files are not translated. However,

NFS

includes

a

binary record length as a prefix for variable-length records. (Check

implementation;

you may have

to use

special

parameters.)

Note: Some

NFS

systems

do not

supply

files.

ACIF treats a file that contains only structured fields (MO:DCA or AFP LIST3820) as a special case. You can always transfer such a file a special record separator, and ACIF can always read it because stru self-defining, containing their own length; ACIF handles print files and resources (form definitions, fonts, page segments, overlays, and so on way.

Invoke Medium Map (IMM) Structured Field

Retrieval programs			must	be	able	to detect	which	medium	map	is activ
that	pages	are	reprinted		(or viewed) using the correct medium map.
the	correct	medium map		is	used,	use the	Active	Medium	Map	triplet a

Medium Map Page Number triplet (from the appropriate Index Element [I structured field in the index object file), which designate the nam

explicitly	invoked IMM	structured		field	and the number of pages prod
IMM was invoked. The retrieval system					can use this information to dyna
