* 12-Sep-2021 *HELP uses subject lookup, *HELP MOS, *HELP HOSTFS.
|
||||
* 25-Oct-2021 Implemented *BASIC.
|
||||
* 07-Oct-2022 *CLOSE is a host command, fixed *EXEC.
|
||||
* 08-Oct-2022 Rewrote *TYPE, *DUMP, *SPOOL, shares code with *EXEC.
|
||||
* Sorted command table, added *HELP FILE.
|
||||
|
||||
|
||||
* COMMAND TABLE
|
||||
***************
|
||||
* Table structure is: { string, byte OR $80, destword-1 } $00
|
||||
* fsc commands
|
||||
CMDTABLE ASC 'CAT' ; Must be first command so matches '*.'
|
||||
* Commands are entered with A=command byte with b7=1
|
||||

|

* Ok, let's get around to sorting these
