- Short name: IFUBL
- Long name: If (Unsigned Byte, Long Jump)

Arguments
- const Bit[4] B1: First memory bank to access.
- const Bit[4] B2: Second memory bank to access.
- const UByte A: Address, from the first bank, of the value to retrieve.
- const UByte V: Unsigned value to compare the retrieved value to, or address from the second bank of the value to retrieve.
- const UByte C: Type of comparison to perform.
- const UShort E: Amount to jump if the comparison does not hold.
Description
This is similar to the IFUB opcode, but it allows a jump of more than 0xFF if the comparison does not hold. This opcode is used if the ‘if’ block will be longer than 0xFF.
