[X] Programs that are linked with Standalone checked (on) can only be debugged with Turbo Debugger.

You can still run these programs in Borland Pascal, however.

The Standalone option produces complete debugging information for a module only if that module has been compiled with the Options│Compiler Debug Information option checked.

Standalone produces local symbol information for a module only if that module has been compiled with the O│C Local Symbols option checked.
