JMP allows for custom programming and script development via JSL, "JMP Scripting Language". JSL is an interpreted scripting language which is executed at runtime, and provides for manipulating JMP application platform objects in a coherent and coordinated way. JSL is capable of creating complex object orientated GUI and data visualization toolsets in the JMP application environmant. JSL can also be accessed externally via COM (Windows). The use of JSL in the JMP environment can greatly extend the usefulness of JMP in the applied statistics setting.

Octoplus develops customised JMP Scripts to assist the user with the analysis of data that is of a repetitive nature. Or automates the link to other analysis systems such as SAS and R.
