CHANGE

Syntax CHANGE old_drv1$ TO new_drv2$
Location TinyToolkit

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 “<*>”.

Example

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.

NOTE

If a device name is in ROM (eg. possibly mdv on QLs without floppy disk drives), the error -20 (read only) will be reported.

CROSS-REFERENCE

FLP_USE and RAM_USE work similarly.
