I need to substitute a pair, regardless where and how often it occurs:

But I do not get output when the string is not here. How can I let the whole string through if there isn't a match? I can handle it otherwise, but think it's just a small tiny little sweet sign to add to the regex ...

From a string like this:
68 97 115 32 44 32 111 100 101 114

I need to substitute a pair, regardless where and how often it occurs:
[regexp "32 44" @substitute "95"]

regex idiot here ...

i hope you are actually sending a string (a symbol), and not a list of numbers?

Input lists are automatically treated as string (symbol).

String/numbers, mhm ... I think it's both :-)

regexp output when no match?
