Table 33 shows the relational operators. These 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 is
less than string B if it is a leading substring of
string B, or if the left-most character in which
the two strings differ is less in string A than
in string B.
Arithmetic values are unsigned, so the value of 0>-1 is {FALSE}.
