Audit trail of masterfile changes

[Art, Clifford]

Anyone have a low maintenance method of writing audit trail records to a
file when users update masterfile records.
We want to keep the following info on a file so the users can see it:
user
date
time
masterfile name
masterfile field
changed from
changed to

We currently call a cobol program in the pre-update procedure passing the
masterfile record.
The cobol program reads the original record and compares all the fields one
by one writing 
the audit trail records. It works but is a lot of work to maintain as our
masterfiles are
constantly changing.

The audit file option doesn't seem to help as it only stores an after image
of all the fields changed.
Anyone have a better, preferably low maintenance way of doing this...
