A numeric value may also be expressed as a string literal of up to
four characters. The string literal must begin and end with the
single quote mark ('). The numeric value is interpreted as the
concatenation of the ASCII values of the characters. This value is
right-justified, as any other numeric value would be.
Evaluation of an expression is always from left to right unless
parentheses are used to group part of the expression. There is no
operator precedence. Subexpressions within parentheses are
evaluated first. Nested parenthetical subexpressions are evaluated
from the inside out.
Valid expression examples:

45+99
&45+&99
@35+@67+@10
%10011110+%1001

The total value of the expression must be between 0 and
$FFFFFFFF.
Address as a Parameter
Many commands use addr as a parameter. The syntax accepted by
167Bug is similar to the one accepted by the MC68040 one-line
assembler. All control addressing modes are allowed. An "address
+ offset register" mode is also provided.
