--------------------------------------------------

It is written in C which is compiled with Microsoft Visual C++ 6.00
package (does not use the C++ features and it's pure C program)
plus Borland C++ 3.1 for 16-bit version.

The source code is boring... Here it is. The whole thing!

The conditional compiling makes the source code hard to read...

int main(
int argc,
char* argv[])
{
int retval;
__try {
retval = 0;
main_chk_version();
main_do_args(argc,argv); // process the command 
arguments
retval = main_do_logfiles(); // process creation of 
various log files

#ifdef _WIN32 // [ 32-bit case ##############################################
if (!retval) retval = main_do_license(); // process license issues
#else // 32-bit case ] [ 16-bit #####################################
if (!retval) read_licfile(0); // set license data
#endif // 16-bit case ] ##############################################

if (!retval) retval = main_do_srcdst(); // process src 
specifier and dst specifier
if (!retval) retval = main_chk_srcdst(); // detect src/dst 
error conditions
if (!retval) retval = main_do_excludes(); // set exclusion 
directories
if (!retval) retval = main_do_warning();
if (!retval) retval = main_do_datman();
if (!retval) retval = main_do_miscinit();
if (!retval) retval = main_do_thework(); // do the real work
kexit(retval);
return(exit_code); // actually, it never 
comes here
}
#ifdef _WIN32 // [ 32-bit case ##############################################
__except (1) {
error_trap();
kexit(ECODE_FATAL);
return(ECODE_FATAL);
}
#endif // 32-bit case ] ##############################################
}

The whole thing is a little over 23,000 lines. You need to sign a 
non-disclosure
agreement, and pay $23,000 to maintain XXCOPY by yourself for your own company.
But, this is not an educational material. It has not much innovative 
techniques
in programming. The strength of XXCOPY is not in the programming technique.
Rather, it is the design of it -- which is for the public to see through our
extensive documentation. Also, the working Freeware allows you to examine the
working program which is much better way to uderstand the source code.

So, if Microsoft decides to duplicate the XXCOPY program, they can just assign
the "XXXCOPY" project to a couple of their mediocre programmers and give them
the whole published XXCOPY docs and the freeware to look at and give them
an office and 12 months. They will have XXCOPY-knock out product.

Remember, XXCOPY is not a publich-domain software.
