Relational operators
Table 3-9 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
•
program-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}
.
