Maybe you could just loop between column 1 and the maximum column:

dim cCtr as long
for cctr = 1 to activesheet.columns.count
'do something
next cctr

Say you want to loop through rows looking through columns:

dim cCtr as long
dim rCtr as long

for rctr = 1 to 10
for cctr = 1 to activesheet.columns.count
msgbox activesheet.cells(rctr,cctr).value
next cctr
next rctr

If this doesn't help (and I'd be kind of surprised if it did!), you may want to
add some more detail to your question.

I have a macro that loops from column A to column IV(the last column in
Excel). Once the last column is read how can I cause my macro to restart at
the column A again? Can I set my macro to return to column A after it reads
column IV. What would be the macro syntax for that? Thanks.
