| Hex Code: | 00 | 01 | 00 | 00 | 00 | 00 | 00 | NN | unconditional |
|---|---|---|---|---|---|---|---|---|---|
| 00 | M1 | 00 | XX | 00 | YY | 00 | NN | M=1-7, Compare register XX to register YY | |
| 00 | M1 | 00 | XX | KK | KK | 00 | NN | M=9-F, Compare register XX to constant KKKK |
| Restrictions: | This command is permitted in Pre and Post commands only. |
| Action: | The GOTO command transfers control within the same PGC to the line number in byte 7. |
| Order: | If a compare is specified, it is performed first. If the conditions are met the GOTO is executed. |
| Comments: | Line numbers are relative to the group of commands (pre or post). |

| 1 | RegX & RegY | 9 | RegX & K | BC | Bitwise compare, the two operands are anded, if the result is non-zero the condition is true |
| 2 | RegX == RegY | A | RegX == K | EQ | If the two operands are equal the condition is true |
| 3 | RegX != RegY | B | RegX != K | NE | If the two operands are not equal the condition is true |
| 4 | RegX >= RegY | C | RegX >= K | GE | If RegX is greater than or equal to the right operand the condition is true |
| 5 | RegX > RegY | D | RegX > K | GT | If RegX is greater than the right operand the condition is true |
| 6 | RegX <= RegY | E | RegX <= K | LE | If RegX is less than or equal to the right operand the condition is true |
| 7 | RegX < RegY | F | RegX < K | LT | If RegX is less than the right operand the condition is true |
