| Hex Code: | 20 | 07 | 00 | 00 | 00 | 00 | HH | NN | unconditional |
|---|---|---|---|---|---|---|---|---|---|
| 20 | M7 | 00 | XX | 00 | YY | HH | NN | M=1-7, Compare register XX to register YY | |
| 20 | M7 | 00 | XX | KK | KK | HH | NN | M=9-F, Compare register XX to constant KKKK |
| Action: | The LinkCN command jumps to Cell "NN" (byte 7) in the current PGC, and can set SPRM 8 to highlight a different button by setting "HH" (byte 6) to 4*button. |
| Order: | If a compare is specified, it is performed first. If the conditions are met the LinkCN is executed. |
| Comments: | Restricted to the current PGC. |

| 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 |
