Thank you for your reply.

So if I am understanding correctly (feel free to admit my 
ignorance):

1. implib is required to generate a dmd compatible import library 
from an .dll

2. implib only works for C calling convention only

Therefore, D can only call C and D compatible .dll's?

Obviously I am being dumb about something, because learning and 
playing around with D I have written several windows programs (XP 
and 7) that call Silverfrost FORTRAN .dll's (please see 
http://rrroberts.50webs.com/cobindex.htm) using extern (Pascal) 
{...}.  The FORTRAN .dll's were produced by the Silverfrost 
SLINKER, then produced an .lib file from that .dll using DMD's 
implib.  And I am now doing the same thing with Free Pascal.

And before anyone says COBOL and FORTRAN are dead, COBOL is still 
widely used in banking back-end applications, and FORTRAN is used 
in engineering applications.

Again thanks for your reply.
