The source code is tokenized linearly (single-pass), using simple rules about which characters are allowed to be adjacent within a token. When a character is encountered that cannot be adjacent to the last character of the current token, the current token is deemed complete and the new character begins a new token. Some characters (such as { or ,) cannot be adjacent to any other characters and are therefore their own token. Others (like > or =) are only allowed to be adjacent to themselves, and can thus form tokens like >>> or ==. Whitespace characters force a boundary between tokens but aren't themselves included in the result. The most difficult character to tokenize is - because it can both represent subtraction and unary negation, and thus requires some special-casing.

Some characters (such as { or ,) cannot be adjacent to any other characters and are therefore their own token. Others (like > or =) are only allowed to be adjacent to other characters within their class, and can thus form tokens like >>>, ==, or >=, but not like =2.

Each of the operands contains both a data value and an addressing move. The data value is described by a decimal number in the range -32768 to 65536. The addressing mode is described by a one-letter prefix to the data value.
