One final comment - perhaps you should consider the += operator? As well, since you are visiting each key-value pair once, each might be appropriate. And, as long as you are using $_, you may way well use its shorthand.

my $YESMapping = 0;


while (my ($key, $value) = each %map) {
    $YESMapping += s/$key/$value/gi;
}

print "Replaced $YESMapping entries.\n"
