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