The last couple of months there have been updates for Kick Assembler. Changes are: Mnemonic extensions forces all addressing modes. You can now use the question mark as notation in expression. Added a fill-byte option. You can now cast values to a numbers or strings by using the .number() or .string() function. Characters now have the same functions as numbers (+,-,*,<,>,<=, etc.). Kick Assembler is a combination of an assembler for writing 6510 machine code and a high level script language.
