ACCESS
From QB64 Wiki
The ACCESS clause is used in a networking OPEN statement. DOS 3.1 or above only!
- 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:
- Requires that the DOS SHARED.EXE program be run for QBasic to use networking access modes.
- 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.
