That discussion has pointers to various examples,

 In general VMS Pascal/VMS Basic code should be maybe 25% shorter
than equivalent C code. But with a descriptor centric API like
SMG$ then it may be more like 40% shorter.
 One could make a nice wrapper in C++ encapsulating the context
and convert between stl::string / C char array and descriptors.

If anyone want to try, then I suggest:
$ CXX/POINTER=32 ...
or you will regret it.
