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. Valid expression examples:
The total value of the expression must be between 0 and $FFFFFFFF.
