Copy and Paste using Range.Copy Method - excel

Question

I am trying to paste values from a bunch of tables into one long list. I have the tables spread across different sheets and the number of rows changes, but the columns do not. Then I am also trying to paste a string value that tells what sheet it came from, but having trouble with the active cell part of the code.
When I first tried it, it did not compile, hence why I came here, to figure out why it did not compile. Going back and forth with urdearboy, below, I was able to get the correct code working here.
I have the following:
sub copypaste()
Dim ws1 as worksheet
dim ws2 as worksheet
dim mas as worksheet
Set ws1 =ThisWorkbook.Sheets("Sheet1")
Set ws2=ThisWorkbook.Sheets("Sheet2")
Set mas=ThisWorkbook.Sheets("Master") 'where I create my list
For Each ws In Worksheets
If ws.Name <> mas.Name Then
LRow = mas.Range("A" & mas.Rows.Count).End(xlUp).Offset(1, 0).Row
wsLRow = ws.Range("A" & ws.Rows.Count).End(xlUp).Row
ws.Range("A2:A" & wsLRow - 1).Copy
mas.Range("A" & LRow).PasteSpecial Paste:=xlPasteValues
ws.Range("B2:B" & wsLRow - 1).Copy
mas.Range("B" & LRow).PasteSpecial Paste:=xlPasteValues
mas.Range(mas.Cells(LRow, 4), mas.Cells(wsLRow + LRow - 2, 4)) = ws.Name 'I need my sheet value in the fourth column, not the third, but simply change the col coordinate in the Cells equation above
End If
Next ws
'In order to figure out the sheet name, I used the following:
Dim rng As Range
Set rng = mas.Range("D2", Range("D2").End(xlDown))
For Each Cell In rng
If Cell.Value = "Sheet 1" Then
Cell.Value = "S1"
ElseIf Cell.Value = "Sheet 2" Then
Cell.Value = "S2"
End If
Next Cell
end sub

Answer 1

This will loop through all sheets, with the exception of Master, and import the values on Column A to Master accompanied by the origin of the data (sheet name).
Option Explicit for good measure.
Option Explicit
Sub copypaste()
Dim mas As Worksheet: Set mas = ThisWorkbook.Sheets("Master")
Dim ws As Worksheet, LRow As Long, wsLRow As Long
Application.ScreenUpdating = False
For Each ws In Worksheets
If ws.Name <> mas.Name Then
LRow = mas.Range("A" & mas.Rows.Count).End(xlUp).Offset(1).Row
wsLRow = ws.Range("A" & ws.Rows.Count).End(xlUp).Row
ws.Range("A2:A" & wsLRow).Copy mas.Range("A" & LRow)
mas.Range(mas.Cells(LRow, 2), mas.Cells(wsLRow + LRow - 2, 2)) = ws.Name
End If
Next ws
Application.ScreenUpdating = True
End Sub
To paste values change
ws.Range("A2:A" & wsLRow).Copy mas.Range("A" & LRow)
to this
ws.Range("A2:A" & wsLRow).Copy
mas.Range("A" & LRow).PasteSpecial xlPasteValues
