Hi,

I am reading the coordinate [x,y,z] from external txt file into an array. My questions are:

  1. how to assign the array to pos type? for example, I have input=[1,2,3], and I define VAR pos position; can I use position :=input? 2) as my position is a VAR (variable) already. When I define VAR pos position; VAR num input{3}; VAR robtarget Target_20:=[position,[0.499999903,0,0.86602546,0],[0,0,0,0],[9E9,9E9,9E9,9E9,9E9,9E9]]; the program has this error: the expression position is not a constant expression. How can I solve this problem?

Thanks!
