F7DEL - delete a record from an indexed file.

Usage:

call f7del(lgu, key [, stat])

Where:

lgu

is the fortran unit number of an open file with the record to be deleted. The file should be open in I/O mode when F7DEL is called.

key

is the key of the record to be deleted. If the file is open in sequential mode the last read will be deleted, and this argument will be ignored.

stat

is character*2 or integer variable where the UFAS status is stored. If an integer variable is used, the status is stored in the upper 2 bytes. A status of "00" indicates successful completion. For other values see the UFAS manuals or the Fortran 77 user manual, DL13.

Description:

F7DEL is used to delete a record from an indexed file.
