Hello, the syntax is flexible it terms of the delimiter character, being borrowed from the sed tool. Practically you can replace / with any other character to make it easier to write your substitution expression.
The ! is used for DBURL because there are / in the content (like: mysql://...) which should be escaped (like: mysql:\/\/:...) if / would be used as delimiter. So, you can use whatever delimiter you want and should be fine, like: "/regexp/subst/flags", "!regexp!subst!flags" or "ZregexpZsubstZflags".
