Hex Code: | 30 | 06 | 00 | 00 | 00 | 4K | 00 | 00 |   unconditional |
---|---|---|---|---|---|---|---|---|---|
30 | M6 | 00 | 00 | 00 | 4K | XX | YY |   M=1-7, Compare register XX to register YY |
Action: | This JumpSS VMGM command jumps to VMG menu type "K" (byte 5 lower nibble) from a menu (system space). |
Order: | If a compare is specified, it is performed first. If the conditions are met the JumpSS is executed. |
Comments: | Restricted to FP and VTSM domains.
The only menu type in the VMG is type 2, "title menu", so the only legal value for byte 5 is 42. Related command for use from a title is CallSS VMGM menu. See Also Jump and Call graphic. |

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 |
