7. Saving JMP Scripts to a Data Table The JMP scripting language (JSL) can be used to reproduce results without performing the analysis using menus. Scripts can be saved to your data table, keeping a record of the analyses you have performed. JMP scripts are dynamic – the analysis is performed on the current data. Scripts attached to a data table enable you to efficiently share your analyses with others. 7
