Hello,  
I need help with this code. I try to check the home position and to set an output if the robot is in home.

VAR wztemporary HomePosition;  
PROC TestHome()

VAR shapedata joint\_space;  
CONST jointtarget home\_pos := [[0, -20, 0, 0, 0, 0],[9E+09,9E+09,9E+09,9E+09,9E+09,9E+09]];  
CONST jointtarget delta\_pos := [[2, 2, 2, 2, 2, 2], [9E+09,9E+09,9E+09,9E+09,9E+09,9E+09]];  
WZHomeJointDef \Inside, joint\_space, home\_pos, delta\_pos;  
WZDOSet \Temp, HomePosition \Inside, joint\_space, O\_HomePosition, 1;

ENDPROC

The errors are:  
“Wrong number of arguments to WZHomeJointDef”  
“Wrong number of arguments to WZDOSet”

Thank you!
