Fw: [Sdcc-user] Problem with the switch statement

[Royce & S. Pereira. <be...@im...>]

Insert a break; before each of the case statements, so that the program
doesnt carry on right upto pos=0x80;
In the present case no matter what the value of pos, it always ends up
containing 0x80;
SDCC is smart enough to figure this out & ignores the earlier case
statements!!
