Description
ADC
TOS = TOS + [DSP--] + C
next element = [++DSP]
IF result > 255
C = 1
ELSE
C = 0
IP = IP+1
Add NEXT plus CARRY to
TOS. Drop NEXT.
ADD
TOS = TOS + [DSP--]
IF result > 255
C = 1
ELSE
C = 0
IP = IP+1
Add NEXT to TOS. Drop
NEXT.
ADD
#literal
TOS = TOS + LITERAL
IF result > 255
C = 1
ELSE
C = 0
IP = IP+2
Add literal to TOS.
ADD_R
