Hey

I've been writing a program using TASM for a 80X86 processor and I have ran into something that may be problematic

I have used int 21h for input (ah=7), according to my documentations the command lets the user insert a single string of numbers into AL, what happens if the inserted number is bigger then 255?

thanks ahead.

If you type in english atleast adjust the text...

It looks as if AH=7 only accepts one character at a time so you get it's ascii value which is 0 to 255

Sorry and thanks.
