* '''const UByteBit[4]''' ''B1'': First memory bank to access.* '''const Bit[4]''' ''BB2'': Memory 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.

Performs a comparison between a retrieved value values from memory (Bank at specific banks and Address)addresses. If '''B2''' is zero, and then the unsigned byte Value given in the argument list. The type of comparison used value retrieved from bank '''B1''', address '''A''' is shown in compared with the table belowvalue specified by '''V'''. If '''B2''' is not zero, then the comparison failsvalue retrieved from bank '''B1''', the script pointer jumps forward by the amount specified in the final argument; the starting offset for this jump address '''A''' is just before compared with the jump value argument itself. This is used to implement if/else functionality in scriptsretrieved from bank '''B2''', as demonstrated belowaddress '''V'''.

The type of comparison used is shown in the table below. If the comparison fails, the script pointer jumps forward by the amount specified in the final argument; the starting offset for this jump is just before the jump value argument itself. This, combined with an appropriate [[FF7/Field/Script/Opcodes/10 JMPF|jump forward]], is used to implement if/else functionality in scripts, as demonstrated below. If the content of the 'if' block following the IFUB line is longer than 0xFF, the 'else' jump argument will also need to be longer than 0xFF, and hence you should use the [[FF7/Field/Script/Opcodes/15 IFUBL|IFUBL]] variant is used instead. If the value or address to compare is larger than 0xFF, you should use the [[FF7/Field/Script/Opcodes/18 IFUW|IFUW]]/[[FF7/Field/Script/Opcodes/19 IFUWL|IFUWL]] variantsare used. If the value you are comparing being compared is negative, you should use the [[FF7/Field/Script/Opcodes/16 IFSW|IFSW]]/[[FF7/Field/Script/Opcodes/17 IFSWL|IFSWL]] variantsare used.

In this example, The 'else' block only executes if it is jumped into by the final argument of the IFUB argument list (thus avoiding the execution of the 'if ' block). Once the value found 'else' block is greater than 0x30executed, script execution just continues and the 0x200 WAIT and RET is executed. Since this is also executed by the 'if' block having jumped forward to skip the script halts for a shorter period of time; otherwiseelse block, this demonstrates that the two code paths converge. In C++ (below) this is the script halts for a long period equivalent of timethe if/else block being completed.
