Working with column map expressions and procedures using Lua functions
You can define a column map expression or column map procedure to mask or transform the data in a column using the Lua scripting language.
You can use most standard Lua functions in a column map expression or column map procedure. In addition, you can use functions that are specific to Optim™. For more information about the Lua scripting language, see the Lua web site at http://www.lua.org. For the Optim-specific functions, see Lua for Column Map expressions and procedures. The current level of the supported Lua release is documented in the “Changes from Prior Release(s)” menu selection, available from the main Optim panel under ISPF. As of the time of this document’s update the supported Lua release was 5.3.4.
