Expression as a Parameter
An expression can be one or more numeric values separated by the arithmetic
operators: plus (+), minus (-), multiplied by (*), divided by (/), logical AND
(&), shift left (<<), or shift right (>>).
Numeric values may be expressed in either hexadecimal, decimal, octal, or
binary by immediately preceding them with the proper base identifier.
If no base identifier is specified, then the numeric value is assumed to be
hexadecimal.
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.
