Hi Babar,

> That's fine but how to convert it into hex

???
Please look at ATEST.LST line 460 - 483.
Than load ATEST.HEX into a simulator, set a break point
at address 01E0h and look what happens after this break point.


Hi Richard and Jay,

on the 8051 its easier to use the "MUL AB" instruction,
since the 8051 can do it.
Also, if numbers above 8 bit must be calculated,
code size and speed was better.
