can I filter lines with a list of alternative OR strings?

[David V Glasgow]

Thanks, Dick!  I’ll play with that and see how I get on.  The filter is in a loop which mostly uses simple strings, so presumably I would need to separate any regex filters into a separate loop using 'with regex'.

I have also learned that this is called “alternation”.  Didn’t know that, so now I can investigate further! 

thanks again
