Compare two memo fields using a macro

[zinrey]

I would like to write a macro in Access 2010 that can compare two memo fields (field and [old].field) and determine if any changes has been made.

To determine if a text field have been changed I can used the 'updated' operator:

if (updated([field]) then
.....
endif

but this doesn't work with memo fields. Anyone got any idea how I can approach this?

Thanks
