- for every single input line, you execute those nested loops 20 x 4 x 26, i.e. 2080 times - quite lengthy for more than a few input lines. Yes, I know no other working alternative.
As already proposed, if you describe what is needed someone could come up with some nifty trick e.g. regex. Pls be aware that if the substitution has taken place in the first loop, another 2079 loops will be executed nevertheless.

I hadn't known that; my thought was that gsub only executed on a match? Maybe something like (and I've tried to make this work for a while):
Code:
# Make a variable for easy access:
IDvar="<sense " vID "." vid "\" level=\"" vl "\" n=\"" VNARR[vn] "\" opt=\"n\">"
# If that variable exists, then run gsub.
if (/IDvar/) gsub(IDvar, vdefSep)
gsub analyses the input line / variable char by char for a match, as does the matching operators, e.g. /.../ - so it parses the input twice. Unnecessary, and costly, esp. for lengthy lines. If you're sure there is only one single match, use sub to stop after that match. BTW, /IDvar/ looks for exactly that literal string, "IDvar", verbatim.

I had made a version with such great notes, but upon finishing it, there was an error which I could fix. Likely I lost a bracket somewhere.
There are editors in them 'thar hills that allow for checking for e.g. unpaired brackets, braces, parentheses. Clever indentation also helps.
