==== Arguments ====

* '''const UByte''' ''B'': Memory bank to access.
* '''const UShort''' ''A'': Address of the value to retrieve.
* '''const Short''' ''V'': Unsigned value to compare the retrieved value to.
* '''const UByte''' ''C'': Type of comparison to perform.
* '''const UByte''' ''E'': Amount to jump if the comparison does not hold.

==== Description ====

This is similar to the [[FF7/Field/Script/Opcodes/18 IFUW|IFUW]] opcode, but the value compared to may be negative.
