Compiler Options, Runtime Conditions

Compiler options specified at the module level affect LibreOffice Basic compiler checks and error messages. Basic syntax as well as Basic set of instructions can be different according to the options that are in use. The less Option, the easiest and tolerant LibreOffice Basic language is. The more Option, the richer and controlled Basic language gets.

Compiler options must be specified before the executable program code in a module.
