Not all the commands will work with Longs.
It appears that statements that were designed to be smaller than the "Full Feature" version, such as DEBUG, or SERIN, still maintain their small size by not using Longs.

Try your previous program with SEROUT2 or HSEROUT and DEC. You'll see things in a whole new light.

P.S. Don't forget to try negative numbers, with SDEC.
