Splitting a string into separate values, but the array length is variable

Question

We are a cabinet manufacturer.  I'm trying to write a report to show the location of individual hinges on a door.  I have a string that will look something like these examples:
60, 540
60, 540, 956
60, 540, 956, 1340
It may have 2, 3, 4, or 5 locations.  (Don't think I've ever seen one over 5).
So I have a formula that says:
Split({Doors.HingeCenterLines},',')[1]
This will return 60 - the first figure in my string.
I need to have all of them separated, but the critical thing is the last measurement.  I need it to be the height of the door minus the last hinge location.  So for an example, if I have a 1400mm tall door, the 4th example string listed above would be generated.  I want my entries to look like this:
60
540
956
60
My string always references the hinge relationship to the bottom of the door, but for the top hinge only, I need it to be based on the distance from the top of the door.
Can anyone help with this?  Thanks in advance!

Answer 1

Try this code please:
whileprintingrecords;
local stringvar array arr := Split({Doors.HingeCenterLines},',');
local numbervar temp;
local stringvar fin_string;
local numbervar i;
For i := 1 to ubound(arr) do
     If i = ubound(arr) then
          temp := {Door_height} - tonumber(arr[i]);
          fin_string := fin_string + totext(temp,0,"");
     else
          fin_string := fin_string + arr[i] + chr(13);
fin_string;
You can then right-click the field > Format Field > Common tab > Check the 'Can Grow' option.
