I would pass an object reference to your function - very minimal impact on
your function.
For example:
Your form has THISFORM.COMMENTS as a property.
Change your function to
x = auditlog('table','key','keyvalue',THISFORM)
Auditlog()
LPARAMETER tcTable, tcKey, tcKeyValue, toObject
* reference toObject.COMMENTS to get your comments
