(j3.2006) OUT_OF_RANGE

[Bill Long]

The OUT_OF_RANGE function for X a REAL signaling NaN and MOLD also of type REAL that supports NaN values, returns .false. according to 

"the result is true if and only if the value of X is an IEEE infinity or NaN that is not supported by objects of the type and kind of MOLD,?

However, the description of the function is:

" Whether a value cannot be converted safely.?

I got a question about the intent of the word ?safely? when the function returns .false. for a conversion that would result in an IEEE exception.   I assume we intended for the function to return .false.  (that is was the Result Value specification says), but then what is the meaning of ?safely? in this context?

Cheers,
Bill
