Awesome, thanks to both of you!

I should mention, the code works on linux but not windows, I get a syntax error only on windows, strange: 

Unrecognized escape \K passed through at c:\t\junk32.pl line 58.
Bareword found where operator expected at c:\t\junk32.pl line 58, near
+ "s/\+\K([-\d]+)\+([-\d]+)$/ ($1 + $deltax) . '+' . ($2 + $deltay) /e
+r"
syntax error at c:\t\junk32.pl line 58, near "s/\+\K([-\d]+)\+([-\d]+)
+$/ ($1 + $deltax) . '+' . ($2 + $deltay) /er"
