/* function prototype */
void checkerrors(void);
int main(void)
{
/* request auto detection */

/* initialize graphics and local variables */

/* check for any initialization errors */

/* install a user defined font file */
userfont = installuserfont("USER.CHR");
/* check for any installation errors */

/* check for and report any graphics errors */
void checkerrors(void)
