Deletes selected records from a file according to record list or selection criteria clauses. It takes the general form:
EDELETE file-specifier [record-list | selection-criteria]
EDELETE requires an implicit or explicit record list, or selection criteria. An implicit list can be provided by preceding the command with a SELECT, GET-LIST or other list-providing command.
EDELETE will immediately delete the specified records.
To clear all the records in a file, use the CLEAR-FILE command.
:EDELETE SALES "ABC" "DEF" 2 Records deleted
Delete the records ABC and DEF based on the explicit list of records.
:EDELETE SALES IF P.CODE = "GHI]" n Records deleted
Delete all records in the SALES file in which the P.CODE field starts with GHI.
:SELECT SALES WITH S.CODE = "ABC" n Records selected >EDELETE SALES n Records deleted
Selects all records in the SALES file in which the S.CODE field contains ABC, and deletes them.
