You can choose other symbols, eg the pipe symbol '\|' or you can choose bracket pairs eg `m{^abc}`. Note that the slash '/' is the default character and using this allows you to omit the 'm' operator, eg `/^abc/`. The usual reason to choosing something other than the '/' is when matching on *nix paths so that you don't have to keep escaping the '/'s, eg `/\/path\/to\/file/` versus `m#/path/to/file#`. You can also choose different delimiters for doing substitution, eg `s\|/path/to/\|\|` or `s{abc}{xyz}`. Note when using paired brackets you need a set around both the "to be replaced" and the "replace with" strings. Cheers, JohnGG	[reply] [d/l] [select]
