Hi sonic,

as LV7.1 doesn't support 64bit integers by default you could

- store 64bit entities in a cluster containing a high and a low 32bit longword

- make your own math routines (atleast +,-,*,/ are easy to embed) by emulating 64bit math with 32bit integers

- read some papers on how old 8bit processors emulated 32bit integer math...

Hi GerdW,

Thanks for your great support.

Now I bulid a DLL by visual C++ to use I64 data and intergrate it in labview 7.1.
