Read/Set a variable value declared in a function from another function

Dear All,
Is it possible to Read/Set a variable value declared in a function
from another function?
f.e.x.
public bool myFunction()
{
int cost;
string ProductName;
Getvalues ("Select cost, ProductName into :cost, :ProductName");
}

Getvalues(string Sql)
{
...
}

How do I set or read the variables cost & ProductName from function
Getvalues? The function is passed only the names of the
variables...please help...

TALIA

Many regards
Jack

Not without passing them into the other function. If you want to modify
them, you will have to pass them in as ref:
public void GetValues(string SQL, ref int cost, ref string ProductName) {
...
cost = ...;
ProductName = ...;
}
