 *  CONOUT.  For getchar() and ungetch( c), the global variable _Lastch MUST be
 *  initialized to 0.  Note that getc( 0) may NOT be equivalent to getchar()
 *  and putc( c, 1) may NOT be equivalent to putchar( c); however, each may be
 *  expected to function normally (using BDOS).  The object file xio.crl MUST
