(j3.2006) Meaning of "reference a variable"
Tue May 29 19:32:40 EDT 2007
Question on terminology (following Mike's concerns). In this example:
real, target :: x
real :: p
Does the write statement "reference" the variable x? Or does it just reference
p? Certainly its execution requires the value of x. But our definition of
"reference" talks about designators:
"A data object reference is the appearance of the data object designator in a
context requiring its value at that point during execution."
The problem is the definite article in "the data object designator", as if
there is only one designator that gets to the same value.
