The following error code is generated when compiling in-line assembly
code in QuickC Version 2.00 if the Quick environment's compiler
option is set for ANSI Compatibility instead of MS Extensions:

   C2065: '_asm': undefined

Any code following the "_asm" keyword also generates syntax error
messages.

To set the required compiler option, use the following procedure:

1. Choose Options.Make.

2. Within Customize Build Flags, choose Compiler Flags.

3. Within C Language, choose MS Extensions.

/Ze, Microsoft Extensions, is the default for the command line compiler,
QCL. This can create a situation where compiling with QCL will not
issue any complaints about _asm keywords, but compiling within the
QuickC environment will view _asm as undefined (if ANSI option is
specified instead of MS Extensions).

The following program works as expected when compiled and linked
at the command line with default options, for example:

qcl testasm.c

/* TESTASM.C */

void main (void)
{
  _asm {  mov ax, 5  }
}
