Variables in macros

[Battwell]

What is correct syntax to set something to a var in a macro ?
I want to use an if statement to check a variable to see if a tool should be probed or not
Tried for an hour - given up !

getcar() and setvar(). But you need to be using version 1.2028

Ah. I'm on 2026. Maybe Why

In earlier versions you could read and write the ivars array, e.g.
ivars[10] = 1.234;
double myvar = ivars[10];

The new Getvar and Setvar functions doing the same, setting the members of the ivars array which are the variables you can code with the # suffix in g-code.

thanks- i couldnt find that command documented anywhere.

Is there a list of vars somewhere, and is there a range that's safe for users to use?

[Battwell]

ok. couldnt get syntax right for old ivars version so i installed 2028.

full syntax that works is
double myvar=exec. Getvar(1); // for variable #1

then used
if(myvar>0)
{

skip this code

}

which works.
except the macro just seems to stop and end after the }
is there a goto function i can use instead ? if so how to write that please

[ger21]

I don't understand what you want it to do?
Can you use "else"?

[Battwell]

it was just to skip my probing section in my m6 macro.
it just doesnt resume after the }
(doesnt run the code after ) i havnt worked out why yet.
maybe adding else will work !

If you want the code to run if myvar > 0, then your code should all be inside of the }.
