I did not know this! Isn’t anyone else shocked and surprised??

Thanks Brian. I looked at matchChunk in the dictionary & it seems to return a boolean, rather than the offset.
The boolean is just whether or not the matchChunk operation was successful; you need to provide variables for the start and end character offsets in the function call:
if matchChunk(myString,"([^\t])",tStart,tEnd) then
put "The offset to the first non-tab character is:" && tStart
-- matchChunk had an error because the regex was bad or something
I know you've moved on, but just for the record...
