to avoid backslash-orgies like this, you might be interested in the qq function operator. The corresponding entry in perlfunc is a bit terse, but see perlop under Quote and Quote like Operators. The nice thing about it is that you can choose the delimiter that you want
Non-bracketing delimiters use the same character fore and aft, but the four sorts of ASCII brackets (round, angle, square, curly) all nest
Your solution could then mutate to e.g.
$mylaunch = qq !START "" "$myexe" "$myfile"! ;
exec("$mylaunch");

(as with "normal" functions, you are allowed to have whitespace between function name and opening delimiter)
