Think in Perl's substitution command format:


subst_exp - is regular expression that can be used to group parts of the 
repl_exp - is used to build the output

Example: you want to remove the first 0 and prefix +44 to a number:

This is an obsolete example, right one now is:
dp_translate("240", "$rU/$rU");

It will do the operations over R-URI username part.
