CitectVBA Programming Reference > CitectVBA Function Reference > String Functions > 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 Strcontains 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.




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

Return Value

Returns the numeric ASCII code value of the first character in Str provided in the argument.
