I'm unfamiliar with Bugzilla, so if I annoy anyone, apologies.
This routine is a puzzle, or else I have completely misunderstood it. The
TRANSFER is obviously spurious, as it merely allows the sort of renaming that
used to be possible with the deprecated EQUIVALENCE statement, were it to be
allowed for parameters.
But, why not
dcabs1 = abs(real(z)) + abs(aimag(z))
relying on proper precision selection (or, supply d prefixes).
Of course, in general the TRANSFER function should work.
Best wishes, RNMcLean somewhere by yahoo.com
