Comments

If string_expression is null, an Illegal Function Call error is returned. If string_expression begins with an uppercase letter, the value returned will be within the range of 65 to 90. If string_expression begins with a lowercase letter, the range is 97 to 122. Numbers 0 to 9 return 48 to 57, sequentially. See the CHR$ function for ASCII-to-string conversion.

Example

X$="TEN"
PRINT ASC(X$)

84 is the ASCII code for the letter T.
