The number of matches is returned, this equals the full match + sub-pattern matches.
nMaxMatch is the maximum allowed number of matches. pos contains the string indices of the matches. Its usage is shown in the routine MatchS. For meaning of mods see ParseMods().

) |
Returns a TObjArray of matched substrings as TObjString's.
The TObjArray is owner of the objects and must be deleted by the user. The first entry is the full matched pattern, followed by the sub-patterns. If a pattern was not matched, it will return an empty substring:
produces: "abc" "a" "" "bc"
