MPE/iX and POSIX Differences
Bytestream Files
Bytestream Files
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.
Build
Creates and immediately allocates a new empty file on disk.
The build command has been enhanced to include this bytestream record type.
Syntax
BUILD filereference
[F]
;REC[[recsize][,[blkfactor][,[U][,BINARY]]]]
[V][,ASCII ]
[B]
The “[B]” is the bytestream record type specification.
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
