Thanks,
I tried the converter but when I entered the command according to the
manual I got an error:

D:\Internet\Download\FreePascal_Lazarus>objconv -fCOFF SPROMEPS.obj
SPROMEPS.coff

Error 2004: Unknown command line option: fCOFF


Then I tried to use a lowercase version (so NOT according to the
manual) and it worked!

D:\Internet\Download\FreePascal_Lazarus>objconv -fcoff SPROMEPS.obj
SPROMEPS.coff

Input file: SPROMEPS.obj, output file: SPROMEPS.coff
Converting from OMF32 to COFF32
Warning 1211: 270 comment records ignored

  0 Debug sections removed
  0 Exception sections removed

So now, I changed the line in SPROMEPS.pas from:

{$L SPROMEPS.OBJ}  { LINK WITH THE SUPERPRO OBJECT FILE }

to

{$L SPROMEPS.coff}  { LINK WITH THE SUPERPRO OBJECT FILE }

and the original error disappeared!

Instead I now have a series of undefined identifiers to deal with:

PROGRESS!

The warning about the $F switch concerns a setting to force far calls,
what is the equivalent in FPC?

And I am not sure that COFF is the correct file type to link
against...
Have to look back on all the posts here and find what is recommended.

But now is dinner time and I will quit for a while.

Thanks to all who provided support to me!
