The value of **Result** can be returned with **OK** (**OK** doesn't calculate). Besides below stated Mnemonics, owner definable constants and functions are allowed. If undefined variables are encountered, the user will be prompted for their value (e.g. Tq and R). Floating point variables defined in the form in which the calculator was invoked, are also available. They are marked with an **{temp}**. In case of a table, the Floating point variables found in the clicked row are available. Comments can be added with a leading blank.
