@STRIP

@STRIP[chars,string]:  Removes the characters in chars from the string and 
returns the result.  For example, %@STRIP[AaEe,All Good Men] returns "ll 
Good Mn".  The test is case sensitive.  To include a comma in the chars 
string, enclose the entire first argument in double quotes.  @STRIP will 
remove the quotes before processing the string.
