Bytestream record formats can exist in both the MPE/iX and
POSIX namespace. The purpose of this new record format is to provide
an emulated file format which exists on character-oriented file
systems, where the user application is responsible for defining
where logical records begin and end.
To create such a file, use the build parameters:
ftp> put <source-file> <target-file>;rec=,,b |
The (b) references the bytestream
record type. Note that no record size is given. This is because
bytestream files always have 1 byte records; any other value would
be overwritten. Similarly bytestream files are always MPE file type
ASCII as opposed to Binary. Regardless of whether they are MPE file
type ASCII or Binary, they may be transferred in either FTP ASCII
or Binary transfer mode.

Creates and immediately allocates a new empty file on disk.
The build command has been enhanced to
include this bytestream record type.
Syntax
[F]
;REC[[recsize][,[blkfactor][,[U][,BINARY]]]]
[V][,ASCII ]
[B] |
The "[B]"
is the bytestream record type specification.
Example A-10 Example:
This sample of a bytestream file, a copy from CATALOG.PUB.SYS
which is a (80) Byte per Record, Fixed ASCII file, to the bytestream
record format which is a (1) Byte per Record Bytestream ASCII file.
:copy catalog.pub.sys,asciifix
:build bytestrm;rec=,,b;disc=2000000
:fcopy from=asciifix;to=bytestrm ;nouserlabels
