what exactly does the trim function do?

Good morning everyone,

Maybe owing to my comprehension difficulties in English, I don't understand well what the trim function does.

Does it remove white spaces / blank only at the beginning and at the end of a string or all the white spaces into the string are replaced?

Will it work with carriage return characters as well (\n)?

Thank you.

Yes, all white space including tab (\t), newline either \r or \n. Example

Code: Select all

a = "\tHello World\t\n\r";
b = a + "123";
c = trim(a) + "123";

If you look at debug dialog, b show 123 below the line. While c use the trimmed a, and it shows 123 right next to the world.

Thank you. So it does work only on white spaces left or right and not in the middle.
