[TRNSYS-users] Problems with dynamic arrays definition in new types

[Diego A. Arias]

Dear Jordi,

I suppose that you are using a parameter to size the arrays (parameters 
do not change with time).  I would use the initialization call (INFO(7) 
== -1) to allocate the arrays.  This call is used to set the size of 
storage arrays and general checking routines.
You can deallocate the arrays during the last call (INFO(8) == -1).
Best regards,

Diego
