Hi, In one PC at the University, each time that I tried to read or edit a macro SW crashes without knowing a reason (no message at all) does somedy has an idea how to fix this? We have the SW student version. My other question is regarding the maximum size of a macro, in another PC where the macros work well I got a message telling me that the maximum size of the file should not be greater than 64Kb has anybody encounter such a problem? What I'm trying to do is to read a lot of points with the "Curve trhough free points", so I recorded the syntax for one single curve and then I created a file with Matlab that will writes the other 200 curves. Maybe there is a better way to do this, perhaps a for loop would work. Can you tell me if there is a better way to do this and how (I'm a beginner with VB for SW) Thanks for the help. Pablo,
