[TRNSYS-users] help abuout programing new compoment

[David BRADLEY]

Duguofu,
   I have never found a very satisfactory way of making an adjustable 
array in a Type. It is possible but I have found that it is more trouble 
than it is worth. What is typically done instead is to define the array 
with a maximum size (set as a parameter in the Fortran code - NOTE that 
this is NOT a TRNSYS component parameter) and then only use what you 
need of the array. For example:

DOUBLE PRECISION myArray
INTEGER maxArraySize
PARAMETER (maxArraySize=100)
DIMENSION myArray(maxArraySize)

  This method was used a lot in Trnsys16 for handling components that 
have a variable number of parameters, inputs or outputs. You can look at 
Type17 as an example. In Trnsys17 access to the parameters, inputs, and 
outputs is typically done through access functions like 
getParameterValue() so you don't need to worry so much about setting up 
the size of the PAR() array the ways you used to.
