>Not true. Clipper still had support files that were needed.

Clipper version 5 was a true native code compiler which made standard OBJ files which could be linked with other OBJ files, even those created with C or MASM, using any linker. It just so happened that you also had to link in the Clipper runtime library into the exe (which was already in native code). This is unlike VFP which is an interpreted language.
