|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.

|register to register||Alternate|
|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|
