Can someone explain the SDK manual a little bit to me.

I am trying to simulate clicking the LNAV button.

The LVAR for it is G03_011_BUT

according to the manual to convert this to an ID

first take out underscores G03011 then G = 17 so the ID is 1703011

This is where I struggle to get this to work.

Set the ID to the L:KLID variable

So basically I should write the LVAR variable to 1703011? tried this but having no luck.

Never mind I figured it out. The is an LVAR NAMED KLID that I need to set to trigger the button. Got it working!
