Shouldn't there be a built-in function to set the end of file
(i.e. truncate an existing file)?

API:
SetEndOfFile_(UseFile(file#))

Hmm... You could set the EOF by changing the length of the file in various ways (rewrite it). EOF, AFAIK, is an OS function that returns true if it is, indeed, the end of the file. It wouldn't make sense to have an EOF somewhere in the middle [:/]

What he wants is make the file shorter, without rewriting it. You can make the file longer, if you write something behind it's end, but there is currently no function for the opposite.

That is what the SetEndOfFile_() API does, it set's the End of the File to the current position (set by FileSeek() for example), so everything after the current position will be deleeted.

Ah, my mistake The only thing I would say about this command is "Use with extreme caution!"
