The way using equivalence statement to map an array with vector is how 
currently xlf initializes vector data. The vector literal part has not yet 
been implemented. They plan to use {/ ... /} (curly braces) for the 
syntax:
vector(real(4)) :: a = {/ 1.0, 2.0, 3.0, 4.0 /}

Is this syntax OK for gfortran?

How could I/O handling affect the intrinsic issue?

Thanks!
