JSL can be used to make GUIs to access data in measurement systems with pre-programmed scripts, such as for SPC. For this to work, JMP® must remember the control limits from the status quo when new data arrives. A second JSL script is needed to connect to a DB and load existing limits for variables if they are present. Control limits can be altered/added manually and updated in the data table or automated with default values and a factor for multiple variables. When others pull the data again from the DB, the control limits are automatically added to the column parameter and go into the SPC. This presentation will provide a live demo and JSL example of how to insert and update data in a DB.
