Hi again elton,

Re-reading your question; perhaps what you mean is that you want to return a
flag to the loop if an error has occurred in the called sub and therefore
want to exit the loop. If so then the following.

At the top of the VBA editor before any subs insert the following declaration.

Public errorFlag As Boolean

Then your loop code like the following.

Sub RunInLoop()
Dim i As Long
errorFlag = False 'Initialize to false

For i = 1 To 100
If errorFlag = True Then
Exit For
End If
Application.Run "SkyDaysHour_X31_H2_Hour"
Next i

End Sub


and include the following code in your called sub

Sub SkyDaysHour_X31_H2_Hour()

'The following line goes immediately prior
'to the line/s that likely to produce error
On Error GoTo SubError

'The code likely to produce error here

'The following immediately after the
'code likely to produce error
On Error GoTo 0 'Resumes errror trapping

'The following 3 lines of code are the
'last lines of code before the End Sub

Exit Sub
SubError:
errorFlag = True

End Sub
