Hi!

There are no simple way of doing that. Basically, you can do following:

#DEFINE ChunkSize 10
...
nHandle=fcreate("OutputFile")
do while !eof()
   copy to ("Temp.txt") next ChunkSize delimited with '`' with character '^' fields ...
   if !eof()
      skip
   endif
   lcStr = filetostr("Temp.txt")
   * process lcStr here using string functions, such as chrtran, strtran etc.
   ...
   fwrite(nHandle,lcStr)
enddo
fclose(nHandle)

Above is the most quick way by using native VFP way. Adjust the ChunkSize to get as best performance as possible - tuning between speed of copy to cmmand+getting file into string AND speed of the string parsing (longer string - slower parsing). Too little value will cause slow down on the copy to command. Too large will slow down the string parsing. String parsing would be quite quick if you will use the quick string parsing algorithm in VFP.

HTH.

I'd prefer not to do it this way if there is a simpler way
