I was also impressed with Mr Horns's new program.  (I assigned it to ->Q's
old spot on the keyboard) 

I think two things should be added to the program but I don't know how
to do one of them.

It would be nice if:

2: { .25 .5 .75 }
1: 10				<-- I can do this one.
DEC2FRAC
1: { '1/4' '1/2' '3/4' }


2: '.5*X-.75'
1: 10
DEC2FRAC			<-- ->Q works this way but I don't know how
1: '1/2*X-3/4'			   to duplicate it.

Someone who understands the HP should disassemble ->Q and find out how
it parses equations and put the same functionality into DEC2FRAC.
Maybe even rewrite it is assembly.
