Change your command line to,
$prog_to_B_run="C:\\bad\\path\\to\\notepad.exe";
Observe results. You need to perform a little fine tuning.
#!perl
$prog_to_B_run="c:\\bad\\path\\to\\notepad.exe";
$stat = system("$prog_to_B_run") || die "$!";print "STAT: $stat\n";

C:\APACHE\USERS\TEST>perl test.pl Bad command or file name No such file or directory at test.pl line 5.
Without a die, your original code will return a zero success, then execute your else block which indicates notepad ran successfully, when actually a "Bad command or file name" error message is generated.
