IsControl (FUN) ¶ FUNCTION IsControl : BOOL Reports whether the rune is a control character. InOut: Scope Name Type Return IsControl BOOL Input diRune RUNE Output eErrorID ERROR

IsDigit (FUN) ¶ FUNCTION IsDigit : BOOL Reports whether the rune is a decimal digit. InOut: Scope Name Type Return IsDigit BOOL Input diRune RUNE Output eErrorID ERROR

IsLetter (FUN) ¶ FUNCTION IsLetter : BOOL Reports whether the rune is a letter (category L). InOut: Scope Name Type Return IsLetter BOOL Input diRune RUNE Output eErrorID ERROR

IsGraphic (FUN) ¶ FUNCTION IsGraphic : BOOL Reports whether the rune is defined as a Graphic by Unicode. Such characters include letters, marks, numbers, punctuation, symbols, and spaces, from categories L, M, N, P, S, Zs. InOut: Scope Name Type Return IsGraphic BOOL Input diRune RUNE Output eErrorID ERROR

IsLower (FUN) ¶ FUNCTION IsLower : BOOL Reports whether the rune is a lower case letter. InOut: Scope Name Type Return IsLower BOOL Input diRune RUNE Output eErrorID ERROR

IsMark (FUN) ¶ FUNCTION IsMark : BOOL Reports whether the rune is a mark character (category M). InOut: Scope Name Type Return IsMark BOOL Input diRune RUNE Output eErrorID ERROR

IsNumber (FUN) ¶ FUNCTION IsNumber : BOOL Reports whether the rune is a number (category N). InOut: Scope Name Type Return IsNumber BOOL Input diRune RUNE Output eErrorID ERROR

IsPrint (FUN) ¶ FUNCTION IsPrint : BOOL Reports whether the rune is defined as printable. Such characters include letters, marks, numbers, punctuation, symbols, and the ASCII space character, from categories L, M, N, P, S and the ASCII space character. This categorization is the same as IsGraphic except that the only spacing character is ASCII space, U+0020. InOut: Scope Name Type Return IsPrint BOOL Input diRune RUNE Output eErrorID ERROR
