Oh, one other thing I should have mentioned: Learn how to use "DebugView".
That will really help you see what's happening on a bar by bar basis. In
the help file search on _TRACE.
Download the file it points to and then populate your code with _Trace
statements so that you can see what's happening a crucial points as your
code executes. Its invaluable when trying to debug looping code. It'll
take some time but will help you understand what's going on.

Tomasz,
that is certainly not the answer I was expecting.I am making a diligent
effort to learn the coding and I have a specific NEED....Perhaps you didnt
bother to read my prior message to the board
I posted the code that I was working with and can NOT get the results
expected from the code descriptions.It is not like I asked the board to code
me a system.I supplied the system which I copied from either the manual or a
user file.I had no problems whatsoever,but when I went into the detailed
trade report and went over the output,I discovered that the supposed scale
out of 50% was not occuring.but rather 86%.After spending several hours on
it,I thought that I may find some help
"I don't have any experience as a pilot but please give me simple
one-page instruction how to fly jumbo-jet from New York to London"
Sorry but this is NOT doable"
Tomasz,your analogy is way off base and I really dont appreciate it.
Allan
