| 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><span class="samp">b</span></samp>’ for a backward reference |
| to a local label from the suffix ‘<samp><span class="samp">B</span></samp>’ for a number in binary notation. |
