Relational operators

Table 28 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.

Relational operators interpret arithmetic values as unsigned. So the value of 0>-1 is {FALSE}.
