The ASC statement allows a QB64 program to change a character at any position of a predefined STRING.



Syntax: ASC(string_expression$[, position%]) = code%


  • The string expression must be predefined.
  • Position is optional. If no position is used, the first position is assumed.
  • The position cannot be greater than the string's length(LEN) or an illegal function error will occur.
  • The ASCII code% value can be any value from 0 to 255.


Example:

a$ = "YZC" ASC(a$) = 65 ASC(a$, 2) = 66 PRINT a$ 'ABC ASC(a$, 2) = 0 PRINT a$

ABC A C
