'
In Interlisp-D, it appears that defining one user interrupt'
turns off any previously defined user interrupt.'
EG':'
	(INTERRUPTCHAR 6 ''(PRINT 6) T)'
sets ^F to print 6. Then typing':'
	(INTERRUPTCHAR 7 ''(PRINT 7) T)'
sets ^G to print 7, but ^F is no longer set. Ie':'
	(INTERRUPTCHAR 6 T) => NIL'
'
