Hello,

after migrating to IDL 4.0.1 I've encountered a problem I haven't had with IDL
3.6.1. Apparently it is no longer possible to CALL_EXTERNAL routines that
return float or double values. IDL complains about the /D_VAL keyword
(although I couldn't find it in the help text):

IDL> print, call_external ('dfloat_shr', 'msf_time', hdr, /d_val)
% CALL_EXTERNAL: Float or double result not possible under ALPHA/VMS

Is there anyout out there who knows a solution without adding a new module
to my FORTRAN library?

Georg.
