Hello all,
I often have wondered if I use
for x =3D 1 to length(something)
is it actually faster (which I have become accustomed to doing) to save =
the length value first?
like:
len =3D length(something)
for x =3D 1 to len do
It's probably buried in the docs and missed it, so dont
crucify me Jiri....

See the attached benchmark program. On my machine under DOS32 Eu on a =
Win98 machine, saving the length saves about .05 seconds total in =
1000000 tests. Most user will not find that significant.
