ONXFLAM Compress Files with FLAM

ONXFLAM [ 'str1'=... [, par ] ] [, flam-par ]

The files marked with the Action Code X will be compressed using the FLAM Access Method. The result after compression is always a SAM file.

To use this Variable Action, the FLAM software product must be available.

'str1'=... Name transformation rules. See page 5-.

par :x: | vsn/device

:x: The compressed files are created on the specified Public Volume Set.

vsn/device The compressed files are created on the specified private volume.

flam-par FLAM-specific parameters, e.g. FC=ISAM,RECFORM=VAR. A full description of the FLAM parameters can be found in the FLAM User Guide, Chapter 3, "Interfaces". FLAM parameters may only be specified as from FLAM Version 2.0.

Notes:

If no FLAM parameters are specified, CFS will substitute the parameter INFO=NO. FLAM will display only error messages on the screen.

Specifying the Variable Action without 'str1' and 'str2', as well as without vsn/device (ONXFLAM [flam-par] ), will cause the compressed file to have the same name as the original. The original file will be overwritten.

The system administrator can set a particular BACKUP level as identifier for compressed files. In this case, CFS will set the file to the required BACKUP level (CAT command) following successful compression. In this way, compressed files can be easily identified by their BACKUP level. (CFS User Option: BACKUP).

Compressed files can be handled in Display mode without first being decompressed. For further information, see the DA FLAM command on page 8-.

When decompressing the data (DFLAM), the BACKUP level is reset to the standard BS2000 value.
