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.

real(kind=r64), | intent(in), | optional | DIMENSION(:) | :: | Par |
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.
FUNCTION DXCoilVarSpeedResidual(SpeedRatio, Par) RESULT (Residuum)
! FUNCTION INFORMATION:
! AUTHOR Fred Buhl
! DATE WRITTEN September 2002
! MODIFIED
! RE-ENGINEERED
! PURPOSE OF THIS FUNCTION:
! Calculates residual function (desired outlet temp - actual outlet temp).
! DX Coil output depends on the compressor speed which is being varied to zero the residual.
! METHODOLOGY EMPLOYED:
! Calls CalcMultiSpeedDXCoil to get outlet temperature at the given compressor speed
! and calculates the residual as defined above

! SUBROUTINE ARGUMENT DEFINITIONS:
REAL(r64), INTENT(IN) :: SpeedRatio ! compressor speed ratio (1.0 is max, 0.0 is min)
REAL(r64), INTENT(IN), DIMENSION(:), OPTIONAL :: Par ! par(1) = DX coil number
! par(2) = desired air outlet temperature [C]

! FUNCTION LOCAL VARIABLE DECLARATIONS:
INTEGER :: CoilIndex ! index of this coil
REAL(r64) :: OutletAirTemp ! outlet air temperature [C]
CoilIndex = INT(Par(1))
CALL CalcMultiSpeedDXCoil(CoilIndex,SpeedRatio,1.0d0)
OutletAirTemp = DXCoilOutletTemp(CoilIndex)
