Old statements for processing SAM and ISAM files

These statements for processing SAM and ISAM files are now only supported for reasons of compatibility. The statements listed in section “File processing” should be used in their place.

@ELIM	Deletes records in an ISAM file. If all the records are deleted then - unlike @UNSAVE – the file name remains present in the catalog.	F mode L mode
@FILE	Supplies a file name as the default value for @GET, @READ, @WRITE (Format 2), @SAVE, @OPEN (Format 2) and @ELIM. It is also possible to predefine a file name that only applies to the current work file (explicit local @FILE entry), or a file name which applies to all the work files (global @FILE entry).	F mode L mode
@GET	Fully or partially reads an ISAM file from disk or tape into the current work file.	F mode L mode
@OPEN (Format 2)	Opens an ISAM file for processing directly on the disk. This file may already exist, may be created before being opened or be created as a copy of an existing SAM or ISAM file. It is only possible to open ISAM files for real processing in work file 0. This be empty or contain a file opened for real processing using @OPEN (format 2).	F mode L mode
@READ	Fully or partially reads a SAM file from disk or tape into the current work file.	F mode L mode
@SAVE	Fully or partially writes the content of the current work file as an ISAM file to disk.	F mode L mode
@UNSAVE	Deletes a BS2000 file and the associated catalog entry.	F mode L mode
@WRITE (Format 2)	Fully or partially writes the content of the current work file as a SAM file to disk or tape.	F mode L mode
