Not sure what I did - must have accidentally hit some keys but when I went to re-compile my script, I have the following errors:
Line 596: Syntax error, unexpected divide, expecting assigned assign, on token /
std.zh, Line 7: Error P01: Failure to parse imported file std_constants.zh
Now I was looking at std_constants in text edit and not sure if I did something there.
My script is more than 9,200 lines long by the way. I checked line 596 and it's an empty line (where I hit enter a few times to separate different scripts.
I had just compiled the script fine shortly before this so not sure what happened and I controlled Z until my last save :'(
