Dear all, possibly silly and pedantic question incoming. Where in a piece of code can I define a derived type? Can they be freely mixed with variable declarations as long as the order is OK (i.e. defined before used)? A quick test and some logic suggests they are just like variables in this sense,…

Yes, these are all R508 specification-construct (in particular, type-declaration-stmt, derived-type-def and type-declaration-stmt again). [image]
