RE: [CAD_CAM_EDM_DRO] Re: G-code---for the new millenium

Hi, Bill Vance:

I'd be interested in viewing the source to BC - It might be worthwhile
rewriting in Pascal to work into TurboCNC. Then, again, it may not.

Thanks for your offer.

|Hi guys;
|
|For those using Linux, (and others if you're enough of a
|programmer), there's
|another option in "bc". Bc is an arbitrary calculator language,
|and even comes
|with an RPN version for Forth and Hewlett-Packard fans. It can do any math
|related functions and use the print command to output, for instance, G-code
|type text.
|
|I've used it for a unit conversion util I typed in from a give
|away sample card,
|and it's pretty versatile. I have the latest bells and whistles
|version GNU
|Copylefted source if you have the old, somewhat limited posix version.
|
|Bill, would posting my util for folks to try be OT here? It's two
|text files,
|one super short, and the other about as big as some of the bigger
|posts I've
|seen here.
|
|Bill
