the GCBASIC compiler give to me the following message of error:

Internal error in TipeOfVar
Internal error in TipeOfVar
Internal error in TipeOfVar

Aborting due to runtime error 6 (out of bounds array access at line 952 of F:/Robotic/GCBASIC/preprocessor.bi::PREPROCESSOR()

I don't understand it because I have no F: drive in my PC and less  a Robotic etc… carpet.

thanks in advance for your sure attention, while I wait your answer.
