HI Guys:

couldn\\\\\\\'t get any better restarting with AppGameKit V2 after more than a year of interruption.

\\\"#option_explicit very clear for me but couldn\\\'t find its value within tier1 as if you declare any variable within #include, it will be noticed by the compiler.

any example to show a good use for it.

the problem was misspelling, this auto declaration create invisible code,
thats why option explicit is much better.
also much people using global vars, u did not see if a var was declared
in a function or outside.

Thanks Markus

but still not making its value. the Idea behind option explicit in c++ is to declare a value that you can initiate else were. which is very useful in functions such as AGK::begin(). were in large programs, you can delare values in another .h file to reduce the use within the begin() function.

however, I don't want this thread to last long but still would like to see example to know the real benefit.

This is not what Option Explicit is for. There is no Option Explicit in C++, it is always on. Declaring a variable as explicit (not Option Explicit) is another thing altogether.

Option Explicit simply states that all variables must be declared before they can be used.

i believe we gave it the name Option Explicit from visual basic 6 and
not thought that in c++ it have other sense.

thanks guys, I got it. I was thinking that it would match declaring variables as explicit in C++.

Yet am I will see any cool use for it as programs get bigger.
