The last two characters $,# indicates hardware requirements for that program.
$ means CGA or EGA, # means 8087 requirements (e.g. 3STARSe7 needs EGA, 8087
and 3STARSc0 needs cga and no 8087.)

This is an update (as of Jan. 14, 1987) of 'Particle Simulation' disk X4321.
I re-organized it into a first part of two disk-series 'Math Software', of 
which the second is 'Differential Equations with parser'. Please ignore my 
previous versions of 'Particle Simulation' and 'Differential Equations' 
programs.

This disk is a Public Domain Software, and may freely copied and distributed
except for commercial purposes, although my second disk 'Differential Equations
with parser' is a shareware recommended for registration.
