The document provides various subroutines using Visual Basic for Applications (VBA) to manipulate Excel workbooks, including loops for iteration (do until, do while, for each, for), functions to close workbooks with or without saving, and a method to hide sheets automatically upon closing the file.

1. LOOP

2. Sub Do_Until()
Dim i As Integer
i = 1
Do
MsgBox (i)
i = i + 1
Loop Until i > 5
End Sub
DO UNTIL LOOP
NEXT: DO WHILE LOOP

3. Sub Do_While_Loop()
Dim i As Integer
i = 5
Do While i = 5
i = i + 1
Loop
End Sub
DO WHILE LOOP
NEXT: FOR EACH LOOP

4. Sub Do_Each_Loop()
Dim sh As Worksheet
For Each sh In ActiveWorkbook.Worksheets
sh.Activate
Range("A1").Value = 15
Next sh
End Sub
FOR EACH LOOP
NEXT: FOR LOOP

5. Sub For_Loop()
Dim i As Integer
Dim j As Integer
For i = 1 To 5
For j = 1 To 30
Range("A" & i).Value = "Month" & i
Cells(i, j).Value = j
Next j
Next I
End Sub
FOR LOOP
