Just started using the PPMAC and encountered some errors when running the forward/inverse kinematic subroutines.

The forward routine seems to be working, but when I add the file inverse.kin in the project I encounter buffer related errors (closed, in use, etc). The same error shows up as early as the compiler finds open inverse (1).

I want to know where exactly this error comes from in my project. Is it something I did not define in the forward kinematics routine?

Below is my code for the forward kinematics routine. Am I setting KinAxisUsed correctly? My machine has 5 axes. Thanks!

csglobal Dz; //B_to_Tip_TCP;
csglobal FwdKinErr;

Dz = 266 ; //B_to_Tip_TCP;
