I received the following message in response to my question about disabling
the QUIT button and since the sender allowed me to post it and I thought it
would be interesting/useful to micro.ti readers:

I find the following CALL LOADS to be useful:
CALL LOAD(-31931,0) -- unprotect the protected X-BASIC program in memory
CALL LOAD(-31806,16) -- disable QUIT key
>83C2 is an interesting address to play around with. It is located in the
Scrath Pad RAM. This address is known as the 'Interrupt Flag' and is a
1 byte bit mapped address.
>83C2
Bit Use
0 On disable all of the following
1 On disable Sprite motion
2 On disable Auto Sound processing
3 On disable the QUIT key( FCTN = )
4-7 not used
CALL LOAD(-31806,128) = bit 0 on
CALL LOAD(-31806,64) = bit 1 on
CALL LOAD(-31806,32) = bit 2 on
CALL LOAD(-31806,16) = bit 3 on
CALL LOAD(-31806,0) = all bits off
CALL LOAD(-31806,48) = bits 2 & 3 on
CALL LOAD(-31806,80) = bits 1 & 3 on
CALL LOAD(-31806,96) = bits 1 & 2 on
