ASC returns the decimal ASCII value of the first character of a string variable. For a list of ASCII codes used with HUNTER Basic see ASCII Character Set.
Y = ASC(X$(3)) PRINT ASC("A")
will print 65
10 T$="AB" 20 PRINT ASC(T$)
will also print 65, since "A" is the first character.
The string argument must be enclosed in parentheses.
ASC is particularly useful for detecting special characters like control codes, and/or distinguishing them from digits 0-9 or characters A-Z.
