Re: (jeffa) Re: Variable Length Parsing

All, Thank you kindly. I tried several of your tactics and got it to break off at the {TCP} (still have more work though. I did not know you could use ^blah in mid stream. I thought it was "beginning of line" (opposite $). I assume that since I () paren'd it, then it WAS the beginning of the next undefined $4 (or whatever number) ?? (again forgive the ignorance with respect to the code and language.)

Yes, ^ can be used to negate a character class as well as anchor a match - it was not the parens that changed context, it was the square brackets (which denote a character class). Check out the docs, in particular, the sentence below xdigit. jeffa L-LL-L--L-LL-L--L-LL-L-- -R--R-RR-R--R-RR-R--R-RR B--B--B--B--B--B--B--B-- H---H---H---H---H---H--- (the triplet paradiddle with high-hat)	[reply]
