I agree that would fail if I were using your example pseudo-code. But I'm not.

I'm beginning from a string variable that may or may not include
characters used in the search pattern. At run-time, the code slices
and dices that string variable to strip any spaces and then add the
label punctuation to create the search pattern. The variable provides
the search pattern, not a literal string.

So when searching the script's plain text fetched and stored at
run-time in another variable, the search pattern will not be found
unless it matches a goto label existing in the plain text. The search
is looking for a literal string matching a variable's value, not for
the variable's name.

The code appended to my last reply to you works.
