In my quest to avoid the table-flashing behavior of JMP I'm trying a different approach. Normally I create an invisible tabulation, and to use the data I make a data table out of it. The data table is easy to use, but unfortunately if you create a lot of them (like I do) you get lots of tables appearing and disappearing.
To prevent the table flashing I'd like to extract the data directly from the tabulation's tree structure. I'm getting close but haven't found the right technique.
Here's an example:
dt = open("$sample_data\Big Class.jmp");
tb = Tabulate(
Show Control Panel( 0 ),
Add Table(
Column Table( Grouping Columns( :sex ) ),
Row Table( Grouping Columns( :age ) )
)
);
This creates the following tabulation:
| sex |
| age | F | M |
| 12 | 5 | 3 |
| 13 | 3 | 4 |
| 14 | 5 | 7 |
| 15 | 2 | 5 |
| 16 | 2 | 1 |
| 17 | 1 | 2 |
To get the tree structure I use these commands:
rtb = tb << report;
rtb << show tree structure;
The relevant portion of the tree structure is here:

I want to extract the values from these three multitblnumcolboxen. How do I do it? This doesn't work:
age_list = rtb[multitblnumcolbox(1)] << Get values;
f_list = rtb[multitblnumcolbox(2)] << get values;
f_list = rtb[multitblnumcolbox(3)] << get values;
Get Items doesn't work either. Thanks for any suggestions!
