SIMPLE.DLL is still included in the installation in case it is needed for legacy code.

For new code and 3D graphics you could use OpenGL (via ClearWin+ %og say). Although there have been complaints about the learning curve for OpenGL, I suspect that SIMPLEPLOT would not be easier to use.

For 2D graphics you could use ClearWin+ %gr/%pl or %og.

There is also Bill Bardsley's SIMFIT library which can be accessed via Simdem.exe/x64_Simdem.exe and is described the help file under FTN95 then SIMFIT. This includes some 3D plotting.

The original (non_native) %pl does not use winop@.

Brilliant, Ken. I missed that - or forgot about it!

So what is SIMPLE.DLL?

SIMPLE.DLL is the 32bit DLL for the SIMPLEPLOT library.

Having peeked at the documentation Ken pointed me to, I think Paul's assertion that SimplePlot 3D is likely to be as difficult as OpenGL is very likely to be correct.

I think that I'll take the very broad hints and do something else!
