ASC is the numeric function that finds the character-string code for the first
character of the string inside parentheses. ASC is the opposite of the CHR$(x)
function, which finds the character for the character-string code number enclosed
in parentheses.
Parameter: any character or key in quotation marks, or a string expression
If you type more than one character in an ASC function, the computer prints
the code for only the first character in the string; all other characters are ignored.
To display the character-string code for a character, put the ASC function in a
PRINT command.
Examples: PRINT ASC("M") Displays the CHR$ code for M.
77
PRINT ASC("||3|") Displays the CHR$ code for the shifted CLEAR
147 key, which is printed as a reversed heart.
PRINT ASC("MAP") Displays the CHR$ code for only the first letter in
77 the string MAP.
