Well you have to cast the int to a float before you print it, but try using dbReadFile like so:

int a = dbReadFile (FILE_NUM);

when i tried it the first way, i got the same compile error as you, but this way there was no error.

Sorry. what i meant to say was:

dbReadFile (FILE_NUM, &a);

dbReadFile takes a pointer to an integer, so a pointer must be used.

I forget which thread I saw this in, but I remember one of the Dark GDK developers recommending using the C++ File I/O (fstream) as opposed to the Dark GDK ones. Perhaps you might try using that instead?

Definitely avoid the GDK file I/O - it's hard to use, inflexible, slow and has no error detection. Use either the C++ stream I/O (http://www.cplusplus.com/doc/tutorial/files.html) or the older but still good C file I/O (http://www.cprogramming.com/tutorial/cfileio.html).

C is better. Mainly because I'm a PHP developer.
