Hm, if the .mod has ,,IMPORT IO'', shouldn't the usage be
,,IO.File'' instead of merely ,,File''?

I think you got it ....
With XDS and ISO compilers you need the very same 'File' IMPORT clause
in the MOD
And yes Martin message points something very important.

No. Import xx; imports qualified only?

It would have to read

FROM IO IMPORT File;

to cause problems.

IMPORT xx imports QUALIFIED idents only
FROM xx IMPORT yy imports yy UNQUALIFIED
AND imports made in DEF is NOT known in MOD and you get an error with
XDS compiler
BUT with Topspeed this will compile ...

DEFINITION MODULE x;
FROM FIO IMPORT WrLn, File;
PROCEDURE Y (f: File);
END x.

------------------
IMPLEMENTATION MODULE x

PROCEDURE Y (f: File);
BEGIN
WrLn(f)
END Y;
END x.

Huh? Is that conforming to the standard?

Well I never read directly ISO standards texts (far too expensive),
but from documents I could read I think that it's Topspeed that is NOT
standard (and far from) - anyway at this time there was not yet a
standard, apart the de facto topspeed one in the PC/MSDOS world.
XDS has a good documentation of ISO language on his site - and as I
understand it each ident must be introduced in the module scope either
by a definition, a declaration or an IMPORT ... and a DEF module is
distinct of the matching implementation.

Thanks to all of you for posting.

I think I managed to figure this out by copying the Import statement
from the DEF File to the MOD File. Now the error goes away - but my
file still has other errors to deal with - so I am not entirely sure
if this worked or not.

Thanks again.
O.O.
