ERASE Delete File/Directory from System

Format

ERASE[ TABLE] name$ [,OPT=options$ ] [,ERR=stmtref ]

Where:

name$	Name of file or directory to be deleted from the system. String expression.
options$	Options to apply to the ERASE. Currently the only valid option is "ALLSEG" to erase all segments of a multi-segmented file.
stmtref	Program line number or statement label to which to transfer control.

Restrictions:
A directory can only be deleted if it does not contain any files. PxPlus is subject to OS rules for the deletion of files or directories. In some operating systems, the ERASE directive is not accepted and will not delete the directory.

Description

Use the ERASE directive to delete the file or directory you name. All disk space that was used by the file or directory is returned to the system. If you erase a file, all data in the file is lost.

Note:
WindX in PxPlus supports the use of this directive via the [WDX] or [LCL] tags; e.g. ERASE "[WDX]somefile.ext". Non-PxPlus versions require you to encapsulate the command in an EXECUTE directive with a [WDX] tag (i.e. EXECUTE "[WDX]..."). See [WDX] Direct Action to Client Machine or [LCL] Access to Users Local Machine.

(The TABLE option was added in PxPlus v6.30.)
(The ERASE logic to delete related segments was added in PxPlus v7.00.)

TABLE Option

The keyword TABLE before the name$ indicates that the value provided is the logical table name for the file as defined in the currently opened Data Dictionary file. See OPEN DICTIONARY.

Multi-Segment Files

If you want to erase the contents of a file that may have multiple segments you need to either include an ,OPT="ALLSEG" or enable the '+E' system parameter. This will assure all segments are deleted from the system.

Example

0010 erase "PRNTFL"
0030 erase "SRTFL1",err=0040
