 * This is an original work by Glenn Scott and is placed in the
 * public domain.
 *
 * Modification history:
 * ---------------------
 *
 *    Rev 1.7   28 Sep 1992 23:48:48   GLENN
 * Deleted #define for FLAG_CARRY as Toolkit v2.1's ftint86.ch has it.
 *
 *    Rev 1.6   03 Oct 1991 18:36:28   GLENN
 * Tim Wong from Nantucket pointed out that this DOS function actually
 * leaves a file handle in AX.  In order to preserve the functionality,
 * I now fclose() that handle if the call is succsessful.
 *
 *    Rev 1.5   15 Aug 1991 23:05:04   GLENN
 * Forest Belt proofread/edited/cleaned up doc
 *
 *    Rev 1.4   17 Jul 1991 22:11:18   GLENN
 * Stripped off chr(0)s in the return value (aRegs[DS])
 *
 *    Rev 1.3   03 Jul 1991 01:08:08   GLENN
 * Changed one line in FT_TEST driver ( cHide == "Y" )
 *
 *    Rev 1.2   14 Jun 1991 19:53:10   GLENN
 * Minor edit to file header
 *
 *    Rev 1.1   12 Jun 1991 02:45:40   GLENN
 * Documentation mods, and convert to new ft_int86() syntax, return value.
 *
 *    Rev 1.0   01 Apr 1991 01:02:24   GLENN
 * Nanforum Toolkit
