Legacy compiler for Fortran code written in 1988.

[GhulamAbbas]

need to compile legacy Fortran code from 1988 that depends on DFPORT and DFLIB.

[GVautier]

I think you just need to change for IFPORT and IFLIB in use statements.

[MarcGrodent]

OK for IFPORT (instead of DFPORT). But IFLIB does not exist => this is IFQWIN (instead of DFLIB).

However, DFPORT and DFLIB are still  accepted although obsolete.

[GhulamAbbas]

I don't want to change anything in the code at the moment; I just need to compile it exactly as it is, even if it uses obsolete libraries. Any help in this regard would be highly appreciated.

Well you are not going to find a decades old compiler here. That code could be compiled with IFX but you code will have been a 32 bit application and only 64 bit is available now. Some changes Will probably be needed.

[MarcGrodent]

It is difficult to help you since you haven't asked any questions. What is exactly the issue here?

[JohnNichols]

This question is asked at least once a week.  Your ONLY solution is to download VS as a good starting point and add ONEAPI.  There are numerous instructions. 

Run the program, find the errors and then ask here how to fix them.  

Trust me you are wasting time doing anything else.  

I compile code from 1968 all the time, it is never affected by the latest compiler. 

Of course if this is your first try at Fortran then you need a text book, as it is a steep climb.

DFPORT and DFLIB are still supplied by Intel Fortran. No source changes needed.
