|Syntax||CHANGE old_drv1$ TO new_drv2$|
This command allows you to rename directory devices. All directory device names are in the form xxxn_, where xxx identifies the drive type (eg. FLP) and n the drive number (1..8).
The most common drive types are:
- RAM - temporary internal ramdisk
- FLP - floppy disk drive (sometimes called FDK)
- MDV - microdrive
- MOS - permanent external ramdisk
- WIN - hard disk drive (sometimes HDK)
- NUL - null device, a dummy device
- DEV - universal devices (also PTH)
(Please see the Devices Appendix.)
CHANGE replaces the xxx part of a device name by a user defined name. This new name can already exist but both parameters must consist of three letters; the use of characters other than letters is possible but not recommended, eg:
CHANGE “flp” TO “<*>”.
CHANGE “ram” TO “mdv” makes the system believe that a ramdisk is a microdrive.
DIR mdv1_ will provide a directory of ramdisk 1, but the device ram1_ (or ram2_, etc.) is no longer recognised. The microdrives themselves cannot be accessed any more until you use: CHANGE “mdv” TO “ram” to restore the normal condition.
If a device name is in ROM (eg. possibly mdv on QLs without floppy disk drives), the error -20 (read only) will be reported.
