- A comparison of two dynamic-length elementary items in a relational condition compares their current lengths, then followed
possibly by a comparison of their contents in line with the following rules:
- If the dynamic-length elementary items are of equal length, their contents are compared as if they were operands of equal size for two fixed-length items.
- If the dynamic-length elementary items are of unequal length, the longer of the two items is considered the greater operand regardless of contents of either operand.

- If comparing a dynamic-length elementary item to a fixed-length item, the dynamic-length elementary item is handled as though it were a fixed-length item whose length is equal to the current length of the dynamic-length elementary item.

Taking the following two dynamic-length elementary items:

01 color1 PIC X DYNAMIC. 01 color2 PIC X DYNAMIC.

You can compare the two items as follows:

MOVE "gray " to color1. MOVE "gray" to color2. IF color1 IS EQUAL TO color2 THEN DISPLAY "color match" ELSE DISPLAY "color mismatch" END-IF.

The result is a 'color mismatch' as the length of
`color1` (dynamically set to 5 at run time) differs from that of
`color2`. As the lengths are determined to be different, the contents of the two items are not inspected.
