how to call a value from another function?

[Paho]

thats not what i mean
test()=3 ; is it porssible

CodeCallback_PlayerCommand(args)
{
self endon("disconnect");
bingband=test();
}
test()
{
slot=3;
return slot;
}

This visible within a given function
Use level or self or return;
return slot;

test()
{
//... use if()
slot="kot";
//... use if()
slot="pog";
//... use if()
slot="";
//...
return slot;
}

CodeCallback_PlayerCommand(args)
{
self endon("disconnect");
//...
if(args[0]=="test")
{
iprintlnbold(test());//output: kot |or| pog |or| "" - using if()
return;
}
//...
}

test()
{
slot="kot";
return slot;
}
if(args[0]=="test")
{
iprintlnbold(test());//output: kot
return;
}
I'm tested it's working
