BrowserUk's solution falls into the category of Stupid Interpolation Tricks in the context of the problem of the OP.

Your opinion noted and dismissed as irrelevant.

Personally, I'd do it this way: printf ("\033[4;%dHEnd Here $a\n", $a+=10 );, but that doesn't answer the OPs question.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
