FA_READ

Reads integer variables from a binary file. For use with F_ROPEN and F_CLOSE. This procedure makes a sequential access to the file, from the previous position. The first call after F_ROPEN reads the first four bytes of the file, each call pushes the reading pointer. To check if the end of file is reached, use F_EOF.
IMPORTANT: Avoid using this function. This function is intended to be obsolete.
