It reads tab delimited files, not with APPEND FROM, but with FGETS(). The reason is that the fields of the import files vary and the file size can be huge. And it also writes files with FPUTS() after having done some sophisticated string manipulation. The speed is still phenominal, thousands of records/lines are processed in a second or so. But the import files can contain 100,000,000 records or even more, so it may still take a while before they're all processed.

Hello,

I must say I am a proponent of C++. C++ can be significantly faster than other programming languages for many reasons. The low level function execute significantly fast, due to the nature of the compiler and the basis of the assembly code.

You can also figure in your own assembly routines for the best optimization, which is something you can't do in FoxPro(that I know of).

Is FoxPro an interpreted language? If so that would add a lot of overhead.
