All expressions are evaluated at assemble-time only; they are never reevaluated during run-time. This
means symbols for unknowns, such as registers (which change at runtime), can not be included inside
expressions.
All constants and symbols within expressions may be 32-bit numbers and the result of the
expression is a 32-bit number. Since the SX is only an 8-bit processor, care must be taken to extract
the appropriate portion of the result for any particular operation. Table 11 – Unary Operators and

sions.
Expressions are evaluated strictly from left-to-right, except when parentheses are present. The following
code demonstrates some simple expression usage.
