Asm68k Assembler Directives

Assembler directives are used in assembly source to generate data and to alter
the assembler's object code generation behavior. This section describes the
various directives supported by asm68k and supplies examples of their typical
usage. The directives are first presented in functional groups, a summary of
which is presented in Table 3.23. For ease of reference, full descriptions of the
directives, including syntax and examples, are then provided in an alphabetically
arranged format.

Debugging directives
The mnemonics for the asm68k assembler directives, like those for instructions,
are written in either all uppercase or all lowercase characters. The lowercase
mnemonics all begin with a period ( . ) and they are extensions to the Motorola
M68000 Resident Structured Assembler. The additional mnemonics (from
asm68) are needed to allow asm68k to support the assembly code generated by
the Sierra Systems compiler, com68. Note that all mnemonics, regardless of the
case they are shown in, can be written in either lowercase or uppercase
characters. When two mnemonics are equivalent and referenced from within this
document, the names of the mnemonics are shown separated by a slash
(e.g., .global / XDEF).
