(j3.2006) question about assignment

[Bill Long]

In a simple, intrinsic assignment

  a = b

is it required that b be defined?  It seems not always, since a and b 
could be structures with an allocatable component, and there is a 
special case where the component of b being not allocated just causes 
the corresponding component of a to be not allocated.  However, the case 
where a and b are allocatable and of intrinsic type is not as clear.  If 
b is not allocated, is the assignment legal and a becomes not allocated, 
or is the assignment not legal?

Cheers,
Bill
