On Page 66 of the "Microsoft Mixed-Language Programmer's Guide"
provided with C Versions 5.00 and 5.10, FORTRAN Versions 4.0x and
4.10, MASM Versions 5.00 and 5.10, and Pascal Version 4.00, the
example program given in section 5.4.2 "Calling C from Pascal --
Function Call" is incorrect. If the Pascal source code in the manual
is compiled, the following errors will occur on the function
declaration line:

                   function Fact (n : integer)  [C]; extern;
                                              ^ ^          ^
 Warning 173  Insert:     ____________________| |          |
    (the compiler is expecting a colon)         |          |
                                                |          |
 315  Type unknown or invalid assumed integer __|          |
      Begin Skip                                           |
                                                           |
 187  End Skip    _________________________________________|

The function declaration in the Pascal program is missing its return
value. If the line is corrected to look as follows the program works
properly:

function Fact (n : integer) : integer  [C]; extern;
