The syntax for moving down a level shares much of the syntax for moving within the level.

Int

Descend to nth child.

First Member

Goes to first member.

Last Member

Goes to last member.

First <element type>

FirstMember<element type>

Goes to first member of given type.

First int <element type>

Go to nth element of given type in members list.

Last <element type>

LastMember<element type>

Goes to last member of given type.

Last int <element type>

Go to nth last element of given type in members list.

Next <element type>

Goes to next element in member list from current position.

Next int <element type>

Goes to next nth element in member list of given type from current position.

Prev <element type>

Goes to next element in member list from current position.

Prev int <element type>

Goes to previous nth element in member list of given type from current position.

<element type> int

descend to nth child of given type.

Examples:

We can use the same example as before but in this case we are positioned at the owning equipment, say /MYEQUI. The current position is defaulted to the start of the list. The member list being:

1 BOX /MyBoxA

2 CYL /MyCylA

3 CYL /MyCylB

4 RTOR /MyRtorA

5 CYL /MyCylC

6 BOX /MyBoxB

7 BOX /MyBoxC

8 CYL /MyCylD

9 BOX /MyBoxD

5

Moves CE to /MyCylC (5th member).

FIRST MEMBER

Moves CE to /MyBoxA.

LAST MEMBER

Moves CE to /MyBoxD.

FIRST CYL

Moves CE to /MyCylA.

FIRST 3 CYL

Moves CE to /MyCylC.

LAST CYL

Moves CE to /MyCylD.

LAST 2 CYL

Moves CE to /MyCylC.

NEXT CYL

Moves CE to /MyCylA (same as FIRST CYL).

NEXT 2 CYL

Moves CE to /MyCylB (same as FIRST 2 CYL).

PREV CYL

Invalid as there are no cylinders before the current position.

BOX 4

Moves CE to /MYBoxD.

In the above examples, the use of NEXT had the same result as using FIRST. The use of PREV was invalid. This is because the current position was off the start. We can change the current position using the END syntax to give more meaningful examples.

For example:

/MyCylB

END

The CE is /MyEqui as before, but with the current position at /MyCylB.

NEXT CYL

Moves CE to /MyCylC.

NEXT 2 CYL

Moves CE to /MyCylD.

PREV CYL

Moves CE to /MyCylA.
