Inserting a value on an appropriate line

[Jalz]

Hi Guys,

 

I'm trying to create a Virtual list, so far it seems to be working great. I populate a global variable called $$MyData and display the results via a VL.

 

Is it possible to to inset a value into line 24 of $MyData using one of the commands or do I have to write a custom function to do this. I've seen there are a couple of custom functions which can extract a line out based on a line number, but Im interested if my $counter says 24, the value goes into line 24 of $$MyData.

 

Many thanks

The nice thing about Custom Functions is that you can write them yourself, like

Let ( [
  lineNumber = Int ( GetAsNumber ( lineNumber ) ) ;
  newLast = ValueCount ( theList ) + 1
  ] ; 
  Case ( 
    lineNumber < 1 ; "Only positive integers for the line number, please!" ;
    lineNumber > newLast ; "Out of bounds error" ;
    lineNumber = 1 ; List ( newLine ; theList ) ;
    lineNumber = newLast ; List ( theList ; newLine ) ;
    Replace ( theList ; Position ( theList ; ¶ ; 1 ; lineNumber - 1 ) ; 0 ; ¶ & newLine )
  )
)
