How about this - I think it implements the function you described in your previous post.



COMPARE:
; VAR1 through VAR6 are in iRAM
MOV SAME,#0 ; clear SAME flag

MOV A,VAR6
SUBB A,VAR5
JNC COMP45
ORL SAME,#00000001b ; set bit 0 if VAR5 > VAR6
COMP45:
MOV A,VAR5
SUBB A,VAR4
JNC COMP34
ORL SAME,#00000010b ; set bit 1 if VAR4 > VAR5
COMP34:
MOV A,VAR4
SUBB A,VAR3
JNC COMP23
ORL SAME,#00000100b ; set bit 2 if VAR3 > VAR4
COMP23:
MOV A,VAR3
SUBB A,VAR2
JNC COMP12
ORL SAME,#00001000b ; set bit 3 if VAR2 > VAR3
COMP12:
MOV A,VAR2
SUBB A,VAR1
JNC COMPEND
ORL SAME,#00010000b ; set bit 4 if VAR1 > VAR2
COMPEND:
