Has anyone ever used SysV's sdb interactive debugger with FORTRAN
programs?

I am running ATT's f77 on a 3B2/400 under SysV 3.0 and programs running
under sdb are compiles with f77 -g.

sdb "sort of works", but fails in some essential (for my applications)
points.

. After a breakpoint, it won't display the contents of REAL*8 arrays.

. It won't display subroutine arguments (Dummy variables).

. Setting breakpoints seems to be a little bit of an art. I can never
  tell where exactly they are going to fall in the source code.

Am I missing something or sdb is not the "powerful debugger" mentioned
in the manual? It is certainly the least flexible one I ever tried.
