Dim sOp As String

sOp = "opening target file"
...
...
sOp = "counting lines already filled"
...
...
sOp = "copying source data table"
...
...
sOp = "saving and closing"
...
These statements are nothing more than one might put in as remarks, but they have the advantage that when an error occurs, the user can be informed what was going on at the time. At its simplest the error handler just needs to contain a single statement like this:
MsgBox "Procedure MyMacro failed while " + vbCrLf + sOp
The value of sOp can also be used to determine the next action (resume, exit, etc). Using this technique in your own macros can make them easier to debug and more friendly for users.
