thanks for the quick reply.
I used the Fanuc Parser as base file and added 'L' as VARNAME in the Lex file.
I didn't declared any variables in de MCF file.
When I add L38 to MCF file and choose DOUBLE its shown correct in the execution window.
But why is one variable already declared before starting the simulation.
How does NX determine the datatype for non declared variables?
Thanks so far
weird things are happening.
After I deleted L38 from MCF it is getting correctly determined in python.
Besides that, both variables are now getting assigned at run time.
Tanks a bunch!
