How to save boolean value even if program is close?

[duckrae]

Hi. I want to ask something.
I want to save boolean value even if program is close.
like sharedpreference in Android.
Is there any function to implement this content?

@duckrae It is not really clear what you want to do.
Is this boolean a setting? If so who is going to use it?
It sounds like your platform is Android, is this correct?

@duckrae since 1956 Read-Write-Memory is a thing. Big shout out to IBM!

So what exactly do you want to do, what platform what os, what condition etc.
