- <p>Upper and lower case are equivalent in register names, opcodes,
- condition codes and assembler directives.
- The case of letters is significant in labels and symbol names. The case
- is also important to distinguish the suffix ‘<samp>b</samp>’ for a backward reference
- to a local label from the suffix ‘<samp>B</samp>’ for a number in binary notation.
