Lutz,
(trim currently works on both sides of a string. It would be nice if it could sometimes be restricted to the left side or right side of a string.
Example
(trim "00239800" "0" LEFT) => "239800"
or
(trim "00239800" "0" RIGHT) => "002398"
The LEFT and RIGHT constants are probably not the best way. It might be better having two
trim functions: (ltrim and (rtrim ?
Currently, I'm using (nth 3 (regex {0*(\d+)} w)) for the left trim.
Eddie.

This is how the new trim in 8.0.8 will work:
(trim " hello ") => "hello"
(trim "----hello----" "-") => "hello"
(trim "0001234" "0" "") => "1234"
(trim "1234000" "" "0") => "1234"
(trim "----hello====" "-" "=") => "hello"
a second syntax can specify a left and a right trim character, an empty string trims nothing.

(trim " hello ") => "hello"
(trim "----hello----" "-") => "hello"
(trim "0001234" "0" "") => "1234"
(trim "1234000" "" "0") => "1234"
(trim "----hello====" "-" "=") => "hello"
a second syntax can specify a left and a right trim character, an empty string trims nothing.
