Very kind offer indeed.
There is another possible approach.
Mentioned computer programs are free and readily available from the net.
Programs are written by ATM for ATM, equipped with substantial help files

the authors are alive and well. They are active members of the ATM list
and very cooperative and friendly persons which never deny to be consulted
if
needed. The programs are:

Investing in learning is always good approach especially in basics.

how to catch the fish will feed him for life" an old saying.
