I'm not sure, but I would like to write sy = 200.0-(float)i; instead
of what you have.

The same.

I haven't been in C-language courses yet, so, this is a wild guess:
Need you declare the type of the trace()? Have you an ANSI-C there?

If the compiler assume that trace() is int-type, that's ok.
But remember, C-language is for human - Fortran is what it is...
I would like to write 'int trace()'.

tt<0.0

I'm sorry about deleting all other code and not telling where all
'errors' are.

Thank you for posting the code!
