RTL "bloat" -- Re: A digression
>I don't directly remember decimal floating point arithmetic routines, but other things imply they were there. However, I know my (shiny new?) MS F77 Fortran complier has such a library (decmath.lib), as well as binary floating point and others. AFAIK MS Fortran 3.3 DECMATH.LIB uses the 80x86 packed BCD math i... 24 Apr 2008 11:50

Interpretation of RECL resolution; help file in CVF
I'm using CVF/DVF V6.6 in F95 mode, after some 3 years away from this. I cannot find where to set the interpretation of RECL, in the direct access mode open statement, to mean bytes and not the default 4-byte chunks, in the Visual Studio envronment. I know setting "form data something", somewhere, to be bytes an... 24 Apr 2008 09:26

I understand that the default size is often 4 bytes for likely performance reasons (register loads and stores, address al... 6 May 2008 23:25
