Editing Spec.isa (section)

==== Literals ====
"<code>add</code>" in the motivating example is a literal.  The user must type this exactly in order for the instruction to be matched.  Of particular note however is that the commas (<code>,</code>) are also literals.
{{note|type=info|The digraph <code>%%</code> must be used if you wish to use a literal <code>%</code> symbol in your assembly syntax, as <code>%</code> is a special character in the ISA language itself.}}
{{note|type=warn|The game does not currently prevent you from using your line or block comment tokens as literals.  However, they will be treated as comment tokens by the assembler and will prevent the instruction from functioning.}}
