Need a regular expression pattern that does not match the beginning of a string.  For example:

abc123      = no match
1abcdi98r = match
deg0abc    = match
.abc            = match

Are you trying to find abc anywhere that is not at the beginning of a string?

Here is a more complete picture.  I am trying to find "(" that is not at the beginning of the string and does not have a -, +, /, *,  or ( directly in-front of it.  I do apologize for my original question being so far off the mark.

Thanks, I am assuming that \)[^-+/*)] would work similarly for the end of a string.  Is that correct?
