| Hex Code: | 46 | 00 | 00 | 00 | 00 | 0S | 00 | 00 | unconditional, indirect |
|---|---|---|---|---|---|---|---|---|---|
| 46 | M0 | 00 | 00 | 00 | 0S | XX | YY | M=1-7, Compare register XX to register YY, indirect | |
| 46 | 0K | 00 | 00 | 00 | 0S | HH | LL | unconditional, indirect, K=1,4-7 Set then Link | |
| 56 | 00 | 00 | 00 | SS | SS | 00 | 00 | unconditional, direct | |
| 56 | M0 | 00 | 00 | SS | SS | XX | YY | M=1-7, Compare register XX to register YY, direct | |
| 56 | 0K | 00 | 00 | SS | SS | HH | LL | unconditional, direct, K=1,4-7 Set then Link |
| Action: | The SetHL_BTNN command sets the selected (highlighted) button number (SPRM 8).
The indirect form sets SPRM 8 to the value in GPRM register "S" (byte 5 lower nibble). The value in the GPRM register should be the button number multiplied by 1024. The direct form sets SPRM 8 to "SSSS" (bytes 4&5). If "K" is 1, 4, 5, 6, or 7 the Set is followed by a link command. |
| Order: | If a compare is specified, it is performed first. If the condition is met the SetHL_BTNN is executed. |
| Comments: | The command can be conditional or be combined with a link command, but not both.
See also SPRMs for information on SPRM 8 values. |

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