I cannot even get started on IVF, due to the differences from CDF (which are far more drastic than I could have imagined). I am working with code that has been successfully compiled on multiple compilers (PGI, g95, FTN95, CDF, Absoft, HP). Now on IVF for the PC, it can't even get past lines specifying a file open and read the first line (!).
The debugger behavior is particularly grating, as it effectively dumps with a "[code name] has triggered a breakpoint", with no apparent explanation for what the issue is. I'm spending hours fighting the interface, rather than identifying coding issues (which I doubt are there, given previous clean compilation on a half-dozen compilers, including some very persnickety ones). If I try to step into the problem area, it complains about "no source available" and stops. There does not seem to be any particular place where it clearly identifies the problem.
Is there a way to make this thing look more "CDF" interface wise, or documentation helping CDF users adapt quickly to IVF? I used CDF for ten years on complicated production Fortran codes with tens of thousands of lines, and now I can't even read a line in a file with IVF.
