the compiler could still treat
"time = 256 * TH0" as
"time = (int16) ((int8) 256 * (int8) TH0)".
without looking at the generated assembler, or stepping thru this code with a simulator, you wouldn't know. and the result of the (int8) version is 0.

if you have unix, try downloading free simulator s51 (search this forum for it) and embedding some test statements in your code, to display the value of "time" after the
first statement.

I'm doing this now



time=256*TH0;

time=time+TL0;



I'm not sure but I think that the teller2 is being my biggest problem.

If it would work correctly,I could determine better if time is ok.
