List View Commands (Cont.)
^LVM
Display a new
position
Display a new position. If select is set, then select that 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.
Display a data list according to a preset sort/ordering view definition. This 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.
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 whatever 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 c 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.
^LVP
Display a new
position
Display a new position. If the select option is set, then select that position.
Syntax:
SEND_COMMAND <DEV>,"'^LVP-<view address>,<index>'"
Variables:
• view address = the address of the view definition
• index = the row number in sequential order (first row is 1)
Example:
SEND_COMMAND Device,"'^LVP-5,3'"
Sets the display position starting at the third row and displays it according to the view
definitions located at address 5.
