Kitty, just to clarify in English, the "less or equal" sign isn't a character in the USASCII character set on which most text-oriented fonts are based. You need a symbol-oriented font to support it. So if you must print one out, you will have the issue of having to somehow substitute in an "extended" character from an enhanced font.
Which leads to the question: MajP - when you did that, which font was loaded? Kitty77 would need to know that because not all font sets support that particular symbol. Many fonts stop at 255 characters and only use multi-national variants like umlauts over A, O, and U, or the special "c" that is in the center of "facade."
Kitty77, if you want to find a font that will support that character, use the character map utility that is one of the system accessories. You load up the font name you want and then can scroll to see what characters are present. You could then determine the hexadecimal value (&hnnnn) you needed for that ChrW function that MajP used; or you would find that your favorite font doesn't support that symbol, one or the other.
