Example

CharactType("A") // the function returns ctAlpha|ctUppercase

CharactType("é") // the function returns ctAlpha|ctLowercase|ctAccent

// Checks whether a character is a letter
IF BinaryAND(CharactType("c"), ctAlpha) <> 0 THEN
Trace("This character is a letter")
END

Syntax

<Result> = CharactType(<Character>)

<Result>: Integer constant (or combination of constants)

Type of studied character:
ctAccent Accented or diacritical character.
The ctAccent constant is always combined with the ctAlpha constant.
ctSpace Space.
ctAlpha Letter.
ctUppercase Uppercase character.
The ctUppercase constant is always combined with the ctAlpha constant.
ctLowercase Lowercase character.
The ctLowercase constant is always combined with the ctAlpha constant.
ctNumeric Numeric character.
ctPunctuation Punctuation character.

<Character>: Character string (with quotes)

Character to use.

Remarks

The character 0 returns 0.
Various character characteristics can be combined: a character can be an accented letter. In this case, the following constants can be combined: ctAccent, ctAlpha, ctUppercase and ctLowercase.
To check a single characteristic (for example, if the character is a letter): it is recommended to test the corresponding constant with BinaryAND or with the "&" operator. For example:

// Checks whether a character is a letter
IF BinaryAND(CharactType("c"), ctAlpha) <> 0 THEN
Trace("This character is a letter")
END
