Nodes of different colours represent the following:
Solid arrows point from a parent (sub)module to the submodule which is descended from it. Dashed arrows point from a module being used to the module or program unit using it. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

Nodes of different colours represent the following:
Solid arrows point from a procedure to one which it calls. Dashed arrows point from an interface to procedures which implement that interface. This could include the module procedures in a generic interface or the implementation in a submodule of an interface in a parent module. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

SUBROUTINE CHKBKS(NBS,NRS)
! SUBROUTINE INFORMATION:
! AUTHOR Legacy Code
! DATE WRITTEN
! MODIFIED Nov 2001, FW: Reverse subroutine arguments NRS and NBS to
! correspond to how CHKBKS is called
! Jan 2002, FW: change error message
! RE-ENGINEERED Lawrie, Oct 2000
! PURPOSE OF THIS SUBROUTINE:
! Determines whether a any vertices of the back surface are in front of the receiving surface;
! if so, gives severe error. Only base heat transfer surfaces are checked.
