Suliman:
I continue attempted to become a programmer,
While D is good enough language, but D is large, so I think it's not the best as first language :-)
I can't understand how to write/change variable from one function by code in another.
In general you can't, and even if you find ways to do it, it's not a good idea.
A simple solution is to define a struct (or a class), with a member variable that you can change as you wish.

D language is too much lax to accept 0/1 as bools, but in general it's quite better to use true/false literals.
And functions in D start with a lower case letter. Bye, bearophile
