What JSL code must be added to the formula code:
New Column („Missing“, Numeric, Nominal, Formula (Is Missing : Name("Column 1")))
to get an dialog with which it is possible to select all columns of a data table?
Thanks for your hint Uday.
Now I'm able to start the dialog and to select a column. However I can't pass the selected column properly to the formula, in order to create the new column with the formula being applied.
You can use the dialog() function to further offer customization. However, if it is not required that the user needs to make a selection, that would be much easier. I would use the examples in Scripting Index for Dialog(), I personally haven't used it much so cannot provide a ready example
