3.6.3. Asm68 Data/Fill Directives
Data directives are used to generate integer and floating-point data. Integer data
can be expressed as integer constants, character constants, or any integer
expression (see section
3.3.7 Expressions
). Floating-point data can be
expressed as either floating-point symbols or floating-point constants. A single
data directive can be used to generate multiple data items. Fill directives are
used to allocate storage, typically for uninitialized data. Table 3.19 summarizes
the data and fill directives for
asm68
. For more information, see sections
3.3.5 Symbols
and
3.3.6 Constants
