What compiler options cannot be specified with the >> IMP OPTION compiler directive?

The compiler options will have no effect when they are specified in the source file with the >> IMP OPTION directive:

   -exec, -la, -lf, -lfo, -lo, -od, sf, -st, -sa, -sl, -sv, -smat and -zmf

For example, the following syntax will NOT move the compiled class to the prg folder:

   >> IMP OPTION "-od=prg"

Instead of using the >> IMP OPTION syntax for these unsupported options, add the option to the command line, or list them in your properties file with iscobol.compiler.options.
For example:

   iscc -od=prg myprog.cbl

or

   iscobol.compiler.options=-od=prg
