PRO/5 Disk Configuration Under MS-DOS and MS-DOS Networks

DSKSYN

A dsksyn line sets up a synonym so that a directory can be logically treated as if it were a disk drive. Additionally, a dsksyn can be used to disable a drive. The dsksyn line has the syntax:

dsksyn dskname directory

The dskname field contains a PRO/5 drive name such as "A:" or "B:". The directory field indicates in MS-DOS the drive and directory that will be used for the given disk name. The path should end with a "/."

A dsksyn line containing a dskname but no directory permanently disable that disk drive for PRO/5.

The DSKSYN option should be used only when necessary to force the configuration of PRO/5 for existing application code; as it is unlikely the same set of DSKSYNs will be used in a new installation of PRO/5.

Utilities supplied with PRO/5 and some applications may not operate correctly if operated in an environment with defined disk drives. Defining the first disk (or current disk while running) should allow most utilities to run correctly.

Examples

In the following example, accessing disk Y: in PRO/5 causes PRO/5 to search the directory /basis/data/ on the current drive:

dsksyn Y: /basis/data/

In the following example, floppy drives A: and B: are disabled by PRO/5 and will not be searched for programs and data:

dsksyn A:
dsksyn B:

It is not necessary to specify a disk in adsksynin order to use it. The first five disk drives are initially considered usable. If you have fewer than five drives, or if you would like to exclude the last drive(s) from the automatic file search, you should specify the LASTDRIVE in the MS-DOSconfig.sysfile. For those MS-DOS systems that do not recognize LASTDRIVE, you should use the DISABLE option or a DSKSYN <drive>: for non-existent drives up to drive E:. PRO/5 generates an !ERROR=17 on any attempt to access such drives.
