12.25 Relational operators
Relational operators act on two operands of the same type to produce a logical value.
The operands can be one of:
Numeric.
PC-relative.
Register-relative.
Strings.
Strings are sorted using ASCII ordering. String A isless than string B if it is a leading substring ofstring B, or if the left-most character in whichthe two strings differ is less in string A thanin string B.
Arithmetic values are unsigned, so the value of 0>-1 is {FALSE}.
The following table shows the relational operators:
