hi Erik,
actually that's what i did as i said in the second posting but when i was trying to compile with Raisonance its saying undefined symbols "DPL" , "DPH", "B", "Acc" and so on. Here's a sample of the code


SWAPDPTR :
PUSH ACC
MOV A,DPL
MOV DPL,R7
MOV R7,A
MOV A,DPH
MOV DPH,R6
MOV R6,A
POP ACC
RET

and its saying undefined symbols ACC,DPL, DPH. The compiler should recognise these terms isn't it???

please do help
thanks:
