Copy-paste loop with skipped values in VBA - loops

Question

I am fairly new to code-writing in general and VBA in particular.
I have tried to write a fairly simple macro that copies values from one cell to another on a daily basis, however I am wondering if there is a way to have fewer variables for the loop counters, in other words, can a loop counter skip certain values?
Private Sub YesButton_Click()
Dim z As Integer
Dim z1 As Integer
Dim z2 As Integer
Dim z3 As Integer
Dim z4 As Integer
Dim z5 As Integer
Dim z6 As Integer
Dim z7 As Integer
Dim z8 As Integer
Dim z9 As Integer
Dim z10 As Integer
Dim z11 As Integer
Dim z12 As Integer
Dim z13 As Integer
Application.Calculation = xlCalculationManual 'turn off autocalc to speed up copy paste process
For z = 5 To 16
Sheet68.Range("H" & z) = Sheet68.Range("D" & z).Value
Next z
For z1 = 21 To 33
Sheet68.Range("H" & z1) = Sheet68.Range("D" & z1).Value
Next z1
For z2 = 38 To 51
Sheet68.Range("H" & z2) = Sheet68.Range("D" & z2).Value
Next z2
For z3 = 73 To 86
Sheet68.Range("H" & z3) = Sheet68.Range("D" & z3).Value
Next z3
For z4 = 92 To 94
Sheet68.Range("G" & z4) = Sheet68.Range("D" & z4).Value
Next z4
For z5 = 100 To 110
Sheet68.Range("G" & z5) = Sheet68.Range("D" & z5).Value
Next z5
For z6 = 115 To 126
Sheet68.Range("G" & z6) = Sheet68.Range("D" & z6).Value
Next z6
For z7 = 131 To 142
Sheet68.Range("G" & z7) = Sheet68.Range("D" & z7).Value
Next z7
For z8 = 149 To 151
Sheet68.Range("G" & z8) = Sheet68.Range("D" & z8).Value
Next z8
For z11 = 157 To 164
Sheet68.Range("G" & z11) = Sheet68.Range("D" & z11).Value
Next z11
For z9 = 169 To 175
Sheet68.Range("G" & z9) = Sheet68.Range("D" & z9).Value
Next z9
For z10 = 180 To 186
Sheet68.Range("G" & z10) = Sheet68.Range("D" & z10).Value
Next z10
For z12 = 191 To 203
Sheet68.Range("H" & z12) = Sheet68.Range("D" & z12).Value
Next z12
Application.Calculation = xlCalculationAutomatic 'turn autocalc back on

Answer 1

Here's an example of how you could re-think your code. You will clearly need to readapt the sample to your own data.
Declare a vector of ranges
The size of it, as many as your intervals are (I counted 14 in your case, but I might be wrong).
Dim ranges(1 To 5)
Dim j As Integer '<-- counter of the ranges
Dim k As Long '<-- counter of your loop
Define your ranges
Here you define, as strings, your specific ranges. In my example I've put random numbers, but in your case should be "5-16", "21-23" etc.
ranges(1) = "1-2"
ranges(2) = "5-10"
ranges(3) = "15-20"
ranges(4) = "25-30"
ranges(5) = "35-40"
Nest two loops
The outside one will loop through the ranges, the inside one will split the ranges and use the lower and upper bounds to loop through your cells
For j = 1 To 5
For k = Split(ranges(j), "-")(0) To Split(ranges(j), "-")(1)
'your code here
'test it with a msgbox:
MsgBox "k is now equal to " & k
Next k
Next j
To sum up
Your code should look something like this:
Dim ranges(1 To 14) '<-- not sure, please check it first!
Dim j As Integer, k As Long
ranges(1) = "5-16"
ranges(2) = "21-33"
'....
ranges(14) = "191-203"
For j = 1 To 14
For k = Split(ranges(j),"-")(0) To Split(ranges(j),"-")(1)
Sheet68.Range("G" & k) = Sheet68.Range("D" & k).Value
Next k
Next j

Answer 2

You can just declare 1 int and use it for every loop. U give it a new value at the start of the loop anyway!
So:
Dim z As Integer
For z = 0 To 10 Step 1
//Do something
Next
For z = 11 To 21 Step 1
//Do something
Next

Sub YesButton_Click()
Dim rngTemp As Range
For Each rngTemp In Range("H5:H16, H21:H33, H38:H51, H73:H86, H191:H203")
rngTemp.Value = rngTemp.Offset(, -4).Value
Next rngTemp
For Each rngTemp In Range("G92:G94, G100:G110, G115:G126, G131:G142, G149:G151, G157:G164, G169:G175, G180:G186")
rngTemp.Value = rngTemp.Offset(, -3).Value
Next rngTemp
End Sub
