so, I decided start using TwinBasic.
after installing it, I started coding for my next project.

the first thing is File-IO, so, CurDir, check if file exists and FileLen.

CurDir worked, returned a string,
after that I needed to get the length of a file, using FileLen, but I get an error. no matter if the file exists or not.

since I want to do everything using internal commands (not API as that could make a mess when cross-platform is here)
Im already stuck. after 1 minute of coding... will wait another year then...
