Righ space are not Trimmed automatically when used in assign values to variable and Std.Str.Find()

Hello Team,

I was told that ECL automatically trims the spaces on the right but when I use it in the STD.str.Find() and also in defining a value it doesn't

Example:
If I define
STRING30 name := 'readfile'
filename := 'thor::ln::'+name

it would not find the file as it will keep the space so either I have to use TRIM(name) or define STRING name without the size.

same applies to STD.str.Find

Std.Str.Find(RIGHT.name_plus_altname, TRIM(LEFT.first_name), 1) > 0
AND
Std.Str.Find(RIGHT.name_plus_altname, TRIM(LEFT.last_name), 1) > 0,
