Math problem

delatorre · Jan 11, 2005

Hi all,
I have a problem in an equation, in example the instruction is:
LD K100 then SUB V3101 (45) then MUL K2487 then OUT V3600.

In other words in the final result of the equation I´m getting other value (3254) diferent of the I´m expecting (136785)

Could somebody direct me please?

I appreciate all your help.

You will have to use LDD, SUBD, etc. for values that large.

Your product is a double word (more then 4 digits) and will reside in V3600 and V3601.

You will need to use all double word instructions.

THANK YOU,

NOW, THE ONLY THING IS THAT I´M MISSING THE FIRST TWO NUMBERS.
THE LAST FOUR NUMBERS ARE CORRECT NOW. (IN THE PRODUCT)

Most likely you're not using doubles for all the calcs, or another fcn is writing over some of the double words.
