This month we are beginning a series of articles describing a double-precision decimal arithmetic package for Applesoft.  Imagine 18-digit arithmetic with none of the screwy rounding errors we are used to seeing in Applesoft's binary arithmetic.

You will also find quick looks at the new Apple //c and a forthcoming set of revised ROMs for the //e.  We finally have the solution to a three-year-old mystery!  You old-timers might remember that in August of 1981 we published a peculiar little "what does this code do?" item from John Broderick.  Well he has revealed answer at long last.


Oops!

There are a couple of bugs in the Intellec Hex Converter we published last month.  To correct the program you should delete line 2240 (the INY) and add a LDA #0 at line 2285.  That will take care of it!  Our thanks to Chaim Palman, of Calcomp, for pointing out the problems.
