Well, I'm rustier at FoxPro than I care to admit, but here's a quick
draft. Folks feel free to poke at it and speed it up:
STORE 0 TO linecount, charcount
start = SECONDS()
hFile = FOPEN("dGrid.py",0)
DO WHILE NOT FEOF(hFile)
theline = FGETS(hFile)
linecount = linecount + 1
charcount = charcount + LEN(theline)
ENDDO
elapsed = SECONDS() - start
FCLOSE(hFile)
? "Lines: "
??linecount
? "Characters: "
?? charcount
? "Elapsed: "
?? elapsed
First pass on an old Pentium-M machine and VFP 7 yields:
Lines: 5294
Characters: 157296
Elapsed: 0.050
Bear in mind that VFP is atrocious at benchmarking fractions of a
second. I believe the accuracy is around 1/50th of second.
