im confused something dont work exatcly how it should work.

var m_temp;
var m1[12];
var m2[12];
var m3[12];
var m4[12];
var m[4];

function main()
{
//for example i have already filled m1-m4 with values
m[0]=m1;
m[1]=m2;
m[2]=m3;
m[3]=m4;

m_temp=m[1];//strangely i got only first m2 value not them all
//possibly you can advice me
}
//So i wished to ask, if is possible to in array put arrays

Here is one way - good way.

You can't do that in C-Script. You have to do it like it's described in the manual:
