- improved help messages
- remove EXIT command, leaving just the QUIT command
- QUIT command now terminates a script recording session rather than
causing the debugger to quit
- renamed granularity to quantum. reframed all commentary/help
messages in these terms
- CARTRDIGE BANK prints error as appropriate
- removed HEXLOAD. functionality subsumed into POKE command
- DISPLAY DEBUG ON/OFF is now DEBUG MASK/UNMASK
o symbols
- fixed table listing
- using index instead of index into array (eye roll)
o cartridge / atari
- fixed bank switching boundary check
- do not allow sdl to output the silence value because some audio
devices turn off as soon as silence is received. this causes sound
to be clipped and in some cases, never to be output at all.
- removed ErrorID, using the error message as the ID
- works just as well and simplifies maintenance
- the messages should be moved to the relevant packages OR to a
locale package. not sure which yet.
