Save a JMP Custom Design to a csv file in a script?

[#1]

I would like to create a script that generates a Custom Design then outputs the Design Matrix to a text file, e.g., '*.csv'.  Here is an example script that generates the Custom Design and a JMP Table containing the Design Matrix.

DOE(
    Custom Design,
    {Add Response( None, "My Response", ., ., . ),
    Add Factor( Discrete Numeric, {1, 2, 3, 4, 5, 6, 7, 8, 9}, "f1", 0 ),
    Add Factor( Discrete Numeric, {1, 2, 3, 4, 5}, "f2", 0 ),
    Add Factor( Blocking, 7, "day" ),
    Add Factor( Categorical, {"v1", "v2", "v3", "v3"}, "f3", 0 ),
    Set Random Seed( 123 ),
    Add Term( {1, 0} ),
    Add Term( {1, 1} ),
    Add Term( {2, 1} ),
    Add Term( {1, 1} ),
    Add Term( {2, 1} ),
    Add Term( {4, 1} ),
    Add Alias Term( {1, 2} ),
    Add Alias Term( {2, 2} ),
    Add Alias Term( {1, 1}, {2, 1} ),
    Add Alias Term( {1, 2} ),
    Add Alias Term( {2, 2} ),
    Add Alias Term( {1, 1}, {2, 1} ),
    Add Alias Term( {1, 1}, {4, 1} ),
    Add Alias Term( {4, 1}, {2, 1} ),
    Number of Starts( 581 ),
    Replicates( 3 ),
    Set Sample Size( 28 ),
    Optimality Criterion( 3 ),
    Make Design,
    Make Table}
);

I searched the JMP JSL Scripting guide without finding a solution.  In the Scripting Index, the "Data Table > Save,Save As" entry looks promising.  It has a example that says:

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
dt << Save( "C:\Big Class.csv" );

I am not sure how to apply this.  After running the DOE script, the table is already open.  How do I get the handle for that table (`dt` in the examlpe) so I can then save it using `dt << Save( "C:\my\path\file.csv" )`?

I think the approach to externalize the "Make Table" message, and placing a handle on it's result is the easiest way to do this

DOEPlatform = DOE(
    Custom Design,
    {Add Response( None, "My Response", ., ., . ),
    Add Factor( Discrete Numeric, {1, 2, 3, 4, 5, 6, 7, 8, 9}, "f1", 0 ),
    Add Factor( Discrete Numeric, {1, 2, 3, 4, 5}, "f2", 0 ),
    Add Factor( Blocking, 7, "day" ),
    Add Factor( Categorical, {"v1", "v2", "v3", "v3"}, "f3", 0 ),
    Set Random Seed( 123 ),
    Add Term( {1, 0} ),
    Add Term( {1, 1} ),
    Add Term( {2, 1} ),
    Add Term( {1, 1} ),
    Add Term( {2, 1} ),
    Add Term( {4, 1} ),
    Add Alias Term( {1, 2} ),
    Add Alias Term( {2, 2} ),
    Add Alias Term( {1, 1}, {2, 1} ),
    Add Alias Term( {1, 2} ),
    Add Alias Term( {2, 2} ),
    Add Alias Term( {1, 1}, {2, 1} ),
    Add Alias Term( {1, 1}, {4, 1} ),
    Add Alias Term( {4, 1}, {2, 1} ),
    Number of Starts( 581 ),
    Replicates( 3 ),
    Set Sample Size( 28 ),
    Optimality Criterion( 3 ),
    Make Design}
);

dt = DOEPlatform<<make table;
dt << Save As(".........");
