Each statement ends with the first occurrence of a newline character (ASCII LF), or of a semicolon (;) that is not within a string operand or between a slash and a newline character. I always prefer to write the function number directly above the syscall instruction. Is it plausible for constructed languages to be used to affect thought and control or mold people towards desired outcomes? Then I want to process it, I already know how to process the number, but only when I've already declared the number in the variable ( Y dw 123), but since I have to ask the user for an input, I have to leave the variable uninitialized ( Y dw ?). So the best way to use that inputted data as character is to convert the data to a character. If you couldn't quite. DB = define byte size variables.
