/ Version   : 1.0
/ Author    : Roland Rashleigh-Berry
/ Date      : 04-May-2011
/ Purpose   : Function-style macro to give you everything following any found
/             target string character.
/ SubMacros : none
/ Notes     : It does an "indexc" on a string to find the first occurrence of
/             any of the characters in the target string and returns all the
/             string after that. If none of the target characters are found then
/             a null string is returned. The search is case sensitive.
/ Usage     : %let rest=%therest(&str,\/);
