Not Follows ('])
Tests if the left operand does not follow the right operand in ASCII collating sequence.
Details
You can produce a Not Follows operation by using the Not operator with Follows in either of the following equivalent formats:
operand A ']operand B
'(operand A ] operand B)
If all characters in the operands are identical or if the first unique character in operand A has a lower ASCII value that the corresponding character in operand B, the Not Follows operation returns a result of TRUE. If the first unique character in operand A has a higher ASCII value that the corresponding character in operand B, the Not Follows operation returns a result of FALSE.
Examples
In the following example, because C in CDE does follow A in ABC, the result is FALSE.
WRITE "CDE"']"ABC",!
WRITE '("CDE"]"ABC")returns FALSE (0).
