Dummy pointers to actual non-pointers allocatable targets

[mEm]

@sblionel

F2008 allows an OPTIONAL dummy argument that is neither POINTER nor ALLOCATABLE to correspond to an actual argument that is an unallocated allocatable or disassociated pointer, in which case the argument is deemed to be “not present”.

Thanks for the clarification. @RonShepard I’m sorry for not having understood your second answer in the first place, don’t know why I got the idea that I had to add OPTIONAL instead of just declaring it as such. Thanks to both for the useful comments.
