Hi,
when you write a macro it is saved as *********.mcs ie Mach Source, then it gets compiled to *********.mcc, ie Mach Compiled.
Compiled code is what actually runs but is not human readable.
If you want to secure a macro, write and save it per normal. Once its compiled and running then remove the *********.mcs and whatever ********* backup files
there are. That would mean there is no user readable code left on the PC.
