8.18 IFCC — Conditional Assembly
Syntax: IFCC
[]
[ELSE]
[]
ENDIF
Description: These directives can be replaced by the IF directive. If IFCC
is true, the statements immediately following the
IFCC directive are assembled. Assembly continues until the
corresponding ELSE or ENDIF directive is reached, after
which assembly moves to the statements following the ENDIF
directive. Nesting of conditional blocks is allowed. The
maximum level of nesting is limited by the available memory
at assembly time.
Table 8-9 lists the available conditional types.
