digits that begins with zero. Hex numbers are specified by a string
consisting of “0x” or “0X” and the hex digits of the number. Both upper
and lower case are allowed. A binary number is specified with “0b” or
“0B”.
4.6 Assembler Declarative Keywords
To do its job efficiently, the assembler needs to recognize a set of
commands that are different from the processor instructions. These
commands, called declarative keywords, control the different aspects of
code generation and are intended for the assembler’s use. In most
cases, the declarative keywords will not produce executable code by
themselves, but must be combined with processor instructions to
generate assembled code.
The declarative keywords are grouped functionally in Table 4.1 . They are
listed alphabetically and defined in the remainder of this section.
