4.2 Source Code Format

Assembly source code consists of statements and white spaces.

White space is one or more spaces or tabs. White space is used to separate pieces of a source line. White space should be used to make your code easier for people to read. Unless within character constants, any white space means the same as exactly one space.

Each statement has the following general format and is followed by a new line.
[label:][mnemonic[operands] ][; comment]
or
[label:][directive[arguments] ][; comment]
