     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
