Code: db 0B8h, 0C3h If you start with a letter a-z then it is a label. Code: B8h = 12345 ; label name "B8h" |

Interestingly, if you used fasm 1.0, that code would be assembled correctly (but you would be missing a whole lot of other features). The earliest versions of fasm expected hexadecimal digits in upper case, with "h" modifier in lower case, and a leading decimal digit was not necessary. For example "Ah" would be considered a number, while "ah" was a register. It was a bad design and I changed it starting with 1.04 release (the same one that introduced the PE output format).

At the same time many people consider a programming language being case-insensitive a bad design. Like those Pascal/Delphi haters. So, why is case-insensitivity “bad” for identifiers but “good” for integer literals, especially when they get mixed with identifiers? IT worldwide need a great review.

Although I once saw a C coding style guide where the rule of indentation or curly braces’ placement was explained by the existence of some auxiliary tool that screwed up if the author didn’t follow the rule suggested. IT worldwide need a great review. |

Python indentation is not optional, it is a requirement.
