3.7.2. Asm68k Symbol Directives
Symbol directives are used to define symbols, declare their scopes, and set their
values. By default, symbols have static scope, i.e., they are local to the files in
which they are defined. In order to be referenced from within other files, they
must be declared to have external scope. Table 3.25 summarizes the symbol
directives for
