ASC()
Abbreviation: A <SHIFT+S>
TYPE: Function-Numeric
FORMAT: ASC(<string>)
Action: ASC will return a number from 0 to 255 which corresponds
to the Commodore ASCII
value of the first character in the string.
EXAMPLES OF ASC Function:
10 PRINT ASC("Z")
20 X = ASC("ZEBRA")
30 J = ASC(J$)
If there are no characters in the string, an ?ILLEGAL QUANTITY
error results. In the third example above, if J$="",
the ASC function will not work. The GET
and GET# statement read a CHR$(0)
as a null string. To eliminate this problem, you should add a
CHR$(0) to the end of the string as shown
below.
EXAMPLE of ASC Function Avoiding ILLEGAL QUANTITY ERROR:
30 J = ASC(J$ + CHR$(0))
