This vector is only called by the operating system, and should not be called
directly. This list just shows the full list of calls that filing systems should implement.
| Function |  | 
|---|
| &00 | *OPT X,Y | 
| &01 | EOF on channel Y being checked with OSBYTE &7F. On exit, X=&FF if EOF, X=&00 otherwise. If Y=&00, (ie, EOF#0) action is implementation specific. | 
| &02 | */ command. XY points to the command text. | 
| &03 | Unrecognised OSCLI. XY points to the command text. The command has already been offered to the paged ROMs via service call &04, and none have responded. | 
| &04 | *RUN command. XY points to filename. | 
| &05 | *CAT command. XY points to any pathname. | 
| &06 | A new filing system is about to take over. This call is generated by filing systems themselves before they start their initialisation. | 
| &07 | File handle range request. Lowest returned in X, highest in Y. | 
| &08 | OSCLI command being processed. This is used to facilitate the *ENABLE command. | 
| &09 | *EX command. XY points to any pathname. | 
| &0A | *INFO command. XY points to the object name. | 
| &0B | *RUN from library. XY points to the filename. | 
| &0C | *RENAME command. XY points to the object names after the command. |
