I'm using TRegex to process stuff that I'm receiving from an RS232 port, actually connected to a Tek 'scope. If I have an incoming message like

ACQ:08080E3150;

and apply a regex such as ACQ:(..){5}; I get a single match which is 50.

If instead I use ACQ:(..)(..){4}; I get two matches 08 and 50, while if I use ACQ:(..)((..){4}); I get 08 and 080E3150.

Can anybody see a way of either specifying a regex where the number of matches is the same as the number of subexpressions matched by a value in braces etc., or of pulling it out of the regex object after the match? This obviously isn't significant in the above case where there's a small amount of input, but it would be nice to be able to match a fixed-size block of data by using something like (..}{512}.
