Nodes of different colours represent the following:
Solid arrows point from one derived type to another which extends (inherits from) it. Dashed arrows point from a derived type to another type containing it as a components, with a label listing the name(s) of said component(s). Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

TYPE ErlValueType
! instance data structure for the values taken by Erl variables, nested structure in ErlVariable
INTEGER :: Type = 0 ! value type, eg. ValueNumber,
REAL(r64) :: Number = 0.0d0 ! numeric value instance for Erl variable
CHARACTER(len=2*MaxNameLength) :: String = '' ! string data types in Erl (not used yet)
INTEGER :: Variable = 0 ! Pointer to another Erl variable
! Might be good to change names to VariableNum and ExpressionNum just to be clear
INTEGER :: Expression = 0 ! Pointer to another Erl expression (e.g. compound operators)
LOGICAL :: TrendVariable = .FALSE. ! true if Erl variable is really a trend variable
INTEGER :: TrendVarPointer = 0 ! index to match in TrendVariable structure
CHARACTER(len=2*MaxNameLength) :: Error = '' ! holds error message string for reporting
END TYPE ErlValueType
