Display a new position

Syntax:

 

SEND_COMMAND <DEV>,"'^LVM-<view address>,<offset>'"

 

Variables:

 

• view address = the address of the view definition

 

• offset = + / - numeric display shift

 

Example:

 

SEND_COMMAND Device,"'^LVM-2,-4'"

 

Shifts the display -4 and displays the list according to the view definitions

 

located at address 2.

 

 

^LVO

Display a data list according to a preset sort/ordering view definition. This

Display a data list according

command tells the view which of the possible orderings to use. Note that the

<sort> field is a bitmask, so that the 3 bit positions may be combined.

to a preset sort/ordering view

definition.

Syntax:

 

SEND_COMMAND <DEV>,"'^LVO-<view address>,<sort>'"

 

Variables:

 

• view address = the address of the view definition

 

• sort = bitmask with the following bit assignments:

 

0x0001 = Sort

 

0x0002 = Reverse

 

0x0004 = Filter

 

Note: Of special note is the reverse bit (0x0002), which reverses the list what-

 

ever order it is currently in. When used on a sorted list, it results in a reverse

 

sort. When used on a reverse sorted list, it results in a forward sorted list. In

 

most cases, the reverse bit should not be used alone, but should be used in

 

combination with the sort bit (0x0003) such that it always results in a reverse

 

sorted list.

 

Possible values for the sort field:

 

0 = None

 

1 = Forward Sort

 

2 = Reverse the current list ordering (may or may not be sorted)

 

3 = Reverse Sort

 

4 = Filter

 

5 = Forward Sort + Filter

 

6 = Reverse current + filter

 

7 = Reverse sort + filter

 

Example:

 

SEND_COMMAND Device,"'^LVO-1,7'"

 

Displays the data list according to the view definitions located at address 1 and

 

filters and reverse sorts the list.
