Generally I recommend a new variable, leaving the $27 field unchanged.
Code:
x27=$27?$27:"default_value";

Now you can use the x27 variable or the original $27.
Another reason is speed: modifying the $27 field denotes a rebuild of the input line $0.
The "value if-else" can be written as an ordinary if-then-else clause
Code:
if ($27) then x27=$27; else x27="default_value";
