Why do that Vlatko? Very likely, he wont need the command line, and I doubt he will EVER need the environ strings.

Also, you tried doing difference with the vb integer division operator. The statement should (probably) be:
Code:
//quotient
int quotient
quotient = n1/n2;

 or...

//quotient
double quotient // most schools like doubles  o.O
quotient = double(n1)/n2;
Z.
