The seventh parameter of this subroutine (actually an entry point to ndvptr) is an array of integers of passed-in length, but the equivalent argument supplied when ndvptx is called (lines 61 to 62 of printe.f and lines 3387 to 3388 of runmd.f) is the "L95"th element of the xx array, which is _REAL_s.

Also, it seems that the parameter in question, called "iscrth", is a scratch array, that is set to an array of pointers inside ndvptr (lines 2510 to 2514 of nmr.f). It looks like it might overwrite parts of xx(). Is that the behaviour we want?

it hasnt blown up yet has it.
Seriously, it'd be great to improve that code, even though it may not
manifest obvious bugs. I glanced at it but gleaned nothing useful;
Id have to play computer or start the debugger.
Maybe Dave has some comments since he's most familiar with it.

Does Darth Vader still program in Fortran?
