Well, you can test any number of statements
after a single 'on error resume next'
and outut or store the Err.Number.

If you do not do an Err.Clear,
the Err.Number will only be overwritten on a new error,
while correct statements would not reset the Err.Number.

on error resume next

q = 8 / 0
ErrNumber1 = Err.Number '' 11

Err.Clear
qwerty
ErrNumber2 = Err.Number '' 13

'''Err.Clear
q = 8 / 1
ErrNumber3 = Err.Number '' 13

Err.Clear
q = 8 / 2
ErrNumber4 = Err.Number '' 0

Here ErrNumber3 would carry the error of the querty statement,
so 'q = 8 / 1' might be construed as being erroneous.
