Precedence

Expressions can be grouped with parentheses (recommended) or you can
rely on the following precedence rules:

Expression Restrictions

The simplified assembly language of the RSP imposes certain restrictions
upon the use of expressions:
• Any identifier used in an expression must be defined before use.
The expression is evaluated at parsing time, it cannot be delayed
until the value of a forward-referencing symbol is determined.
• Identifiers cannot be used in expressions used as a branch target or
as a vector register element.
• Identifiers cannot be used in expressions used in conjunction with
the data initialization directives (.word, .half, .byte).
Identifiers

.word and .half directives, including forward-referencing
identifiers (this is a special case). Note that you can assign an
