JMP will create the JSL version of how to do the conversion, after you go through it interactively.
Here is the JSL taken from the log, after I converted the column interactively
// Change column info: vDate
Data Table( "table1" ):vDate << Data Type(
Numeric,
Format( "m/d/y", 10 ),
Input Format( "m/d/y" )
) << Delete Formula << Set Modeling Type( "Continuous" ) << Set Field Width( 12 );You
