As described on the LuaCOM web page: “LuaCOM is an add-on library to the Lua language that allows Lua programs to use and implement objects that follow Microsoft’s Component Object Model (COM) specification and use the ActiveX technology for property access and method calls.”
A typical application of LuaCOM is to control Microsoft Excel from SIMION. There are a number of examples of that in the SIMION 8 “excel” and “hda” examples. Many other applications can be controlled via COM (e.g. Matlab).
The full LuaCOM manual is available at
For Excel, it may be easier to look at the Lua Excel examples.
LuaCOM is imported by default into SIMION.
