G-Code, CAD, and CAM discussions / Re: G-Code access to Variables

« on: August 12, 2012, 07:18:05 PM »

I have some additional questions to this thread. I now know we can use the variables such as #1, #2, etc... instead of numerical constants. I have used some very simple expressions, but I am interested to use equality expressions to perform some housekeeping function while in a subroutine. Can something like #1=[#1-.25*[#2>0]] work (I know this doesn't) to perform conditional calculations? The equation #1=[#1-.25] works fine. I presume there is more capability to this....I just need a sample or a good reference document to go by.

Can anyone help with reference manuals or good examples?

Thanks,
John
