Local variables

[jorgehrr]

Guys -

Is it better to clear local variables (Parameter 6001 bit 7=0) every time you re set your machine, or it does not matter.
I'm confuse??
If I run
G65P9001X10Z20A100B105 then I change program(different job)
G65P9102X20Z10C250D205 does G65 resets new values????

Regards

Why does it matter? Local variables are volatile so you expect to load them before use.

On a HAAS when you do a G65 call to a subroutine there is a whole new set of local variables created, and these are associated with parameters on the G65 calling line.

Do your own experiments.

Create a program like this:

#1 = 10.0
#2 = 12.0
#101 = #1
#102 = #2
G65 P1000 B22.0
#111 = #1
#112 = #2
M00

N1000
#103 = #1
#104 = #2
#1 = 15.0
#105 = #1
M99

After execution on a 1993 HAAS VF-2 the results are:

101 = 10.0
102 = 12.0
103 = empty
104 = 22.0
105 = 15.0

111 = 10.0
112 = 12.0

Note: on going into the subroutine the local variables in the subroutine are cleared, and those associated with a parameter on the subroutine calling line are loaded with the calling line value.

Changes to a local variable within a subroutine are not passed back out of the subroutine when the subroutine returns.

Local variables that had a value before the subroutine call are unchanged when returning to the calling level.

Thank you very much.

I'm new with macros and I couldn't understand a lot of stuff, I'm doing better now thanks to guys like you that share what they know.

Again, thank you for your help.

Do not hesitate to ask questions when something is not clear. Often a bit of information is what you need to get by an impasse. Learn the fundamentals and develop an intuitive understanding of what you are working on.

One kind of question I do not care for is when someone wants a specific question answered but is unwilling to learn the fundamentals so that they can answer a similar question on their own in the future.

You are 100% Right.
