Re: New CNC software rev finally done...

John, Ballendo,

You'll hear no language bashing from me! Any language is a good
language, if used for and in the scope it was intended. Jon makes good
points on the "safety" of Pascal, and better checking in C++. You CAN
get a little wild in 'C'. One of my favorite cartoons shows a computer
with a large hole blasted in the side, and another programmer observing
it saying: "Yep, looks like a pointer error, all right!". And Ballendo,
yes, I tend to remember the OLD BASIC's, Which ran on TTY's on timeshare
systems, and the 4K BASIC's that first ran on the Altair. BASIC has
certainly come a long way since then! At least I don't have to hand load
the bootstrap loader for the BASIC paper tape!
