Deleting a line in a scrolling list field

[Eric Chatonet]

Hi Scott,

You can use a simple "delete line x of field y" but...
When you say you could probably load the list into into a variable  
and then parse it back to the list field, you are completely right.
This way of doing is much faster.
Always prefer to parse a variable than acting directly on any  
displayed contents.
Why?
Because when working with a variable you only work in REV memory and  
call the system only once to update the display when finished.

For instance:
When deleting line x in a list field 1000 times:

42 seconds using delete line x of fld y without lock screen
26 seconds using delete line x of fld y with lock screen
200 milliseconds putting the list into into a variable and then parse  
it back to the list field

;-)
