Declare it in the general declarations rather than in a Sub.

the thing is im trying to get it to work with only one textbox (kinda like the windows calculator) so i cant really declare it in the general declerations
is there an expression that i can use that will move the variable from one sub to another?

what's stopping you?

otherwise (though I don't rememeber) you could make a variable to be public and do something like form1.textbox1.variableName = whatever

version 5.0? as in VB5? Confused
What is this archaic language you're using.. VB6 has been discontinued.

Yeah, you'll want to use a control array for the numeral buttons, and for the operations as well if you're going to include ( + - * / ).

Something like this:
VisualBASIC:
Private lngDisplay As Long
Private bytOper As Byte

Private Sub cmdNum_Click(Index As Integer)
    lngDisplay = txtAns.Text & Index
    txtAns.Text = lngDisplay
End Sub

Private Sub cmdOper_Click(Index As Integer)
    bytOper = Index
    lblNum.Caption = txtAns.Text
    lblOper.Caption = cmdOper(Index).Caption
    lngDisplay = 0
    txtAns.Text = lngDisplay
End Sub
