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
