oops - what if the array is 65535 bytes ?   :biggrin:
or 32769 to 65535, for that matter

JBE would work if DEC set the carry flag

probably the best code would be...
        sub     cx,1
        jbe     BSort4

that won't work. Here's the explanation.

You have to know the facts before you can distort them.

dedndave

right - that's why i suggested SUB CX,1

So we are on the safe side.

   MSG1 DB "How many integers would you like to enter? (Please enter from 2 to F)", "$"

0fh aka 15 is way below 32769...

dedndave

ok - but the routine was intended to be more generic   :P
you probably knew that - lol

I would never expect an array with more than 32768 members if total memory was only 640k ;-)

dedndave

you're kidding, right ?
i used arrays larger than 64 kb sometimes
