The ACCESS clause is used in an OPEN statement when working over a network.


Syntax

OPEN "file.dat" FOR APPEND [ACCESS {READ|WRITE}] AS #1

Description

  • Valid Options:
    • Default: When specified, all other processes are denied file access.
    • READ: When specified, read access is denied to other file procedures.
    • WRITE: When specified, write access is denied to other file procedures.
    • READ WRITE: When specified any access is denied to other file procedures.


Limitations

  • If another process already has access to a specified file, program access is denied for that file OPEN access. A "Permission Denied" error 70 will be returned. A network program must be able to handle a denial of access error.
