In the statements @ELIM, @GET, @SAVE, @READ and @WRITE (format 2), it is possible to specify '/' instead of the file name if the fixed file link name EDTISAM (for @ELIM, @GET, @SAVE) or EDTSAM (for @READ, @WRITE) has been assigned to the file before it is accessed by EDT.
If the fixed file link name EDTISAM has been assigned to a file then the attributes are read from the Task File Table when the file is opened for reading or writing with @GET or @SAVE. If EDTSAM has been assigned to the file then the attributes from the Task File Table are used when the file is opened for reading or writing with @READ or @WRITE.
If on a write operation, the file attributes differ from the EDT standard format (see the sections on ISAM files and SAM files) then it is only possible to write the files with the statements @SAVE and @WRITE (format 2) if the discrepant attributes have first been entered in the Task File Table and the fixed file link name EDTISAM or EDTSAM has been assigned to the file.
If the symbolic name '/' is specified for a file when a write operation is performed with @SAVE or @WRITE then the unneeded disk storage space is not released after the file is closed and no confirmation query is issued (EDT0903) asking whether an existing file should be overwritten.
