* CMD file is loaded at $4000 and invoked; should return (`rts`) on completion.
* The command line will be present at $200 (`GETLN` input buffer).
* Supports multi-segment, colon-separated paths, e.g. `/hd/cmds:/hd2/more.cmds`
* Commands can use the BI parser for arguments. See `chtype.cmd.s` for an example.
Example:

* `BELL` - beeps the speaker
* `HELLO` - shows a short message
* `ONLINE` - lists online volumes (volume name, slot and drive)
* `ECHO` - echoes back anything following the command
* `CHTYPE` - change the type/auxtype of a file. e.g. `chtype file,T$F1,A$1234`
* `T` (type) and `A` (auxtype) are optional. If neither is specified, current types are shown.
* `S` and `D` arguments can be used to specify slot and drive.
* `CHTIME` - change the modification date/time of a file. e.g. `chtime file,A$1234,B$5678`
* `A` (date) and `B` (time) are optional. If neither is specified, current values are shown.
* `S` and `D` arguments can be used to specify slot and drive.
