It's not necessarily bad; it depends on the situation. The purpose of procedural modules is to promote code re-use and stop you from re-implementing the same thing in multiple places. If it's doing that and it's maintainable, it's fine.

On the other hand, if the modules that the various functions are in is haphazard, the modules are difficult to maintain, or if all programs end up including all four modules, it's worth spending some time coming up with a better design.
