>> Actually, VFP can handle strings only less than 16MB. I put 5000000 ( < than 5MB) just to be sure. So, for files less than 5MB I use now Memo approach and for other files low-level functions. Anyway, I'm not completely satisfied with the speed. Your on-liner seems to be a little bit faster (difference is about 1 sec.), but Mike warned me, that I can have Memory problems with that.

>>Anyway, I think C fll should be faster in this case (I'm not 100% sure, though). If you can find this C code and send it to me with the instructions of creating FLL (I did it once with Cetin's code, but it was ~1,5 years ago), I would really appreaciate it.

I'm sorry. I found the EXE (it actually stripped some commas form an ungly AS/400 file), but not the C source. That was used from a FPW 2.6 app and I think that it was launched with a plain RUN command.

I don't have a C++ in this machine (gladly, I don't need it!), but I have it at home, or in some other's machine. If no other gentleman with a bit more experience does it, tell me and I'll write it. 8-)
