mecej4, tnx for the hints, but it doesn't make sense for me to re-write hundreds of write statements that work perfectly fine when using a DLL created by an old FORTRAN compiler.

Out of curiosity, I pulled my XP machine with an old FORTRAN compiler out of storage, and built the DLL with the same source code (taking out any F95 code). Running the DLL with C++Builder worked just ...

I'm using C++Builder 10.3 to build a GUI for legacy F77 FORTRAN analysis software. A Win32 DLL was built and loads OK. The DLL needs to write results to an external file. The usual WRITE statement wit ...

Thanks mecej4. The "I" format worked.
