Asc

Converts a text string character to its numeric ASCII code value. The Asc function expects the argument Str to be a valid string expression. If Str contains no characters, a runtime error occurs. The Asc function performs the opposite of the Chr function, which converts a number into its string character ASCII code value.

Syntax

Asc(Str)

Str:

A string or expression that can represent a valid text value.

Return Value
