Description

• If <file number> is omitted, data will be written to the record number next to the one
specified by the GET or PUT instruction executed immediately before.
If <record number> is not specified in the PUT instruction executed immediately after the
OPEN instruction, “1” is assigned to <record number> and the data will be written to
record number 1.

written to the specified record.
