Database for VBA

I am building a database catalogue of all our reports and want to include the
SQL and VBA used in the reports. I have added a memo field to hold this data
but the database becomes unstable when I add the VBA (I copy it from MS Excel
and paste it in the memo field). I suspect that Access is trying to run the
VBA.

Could someone suggest how I can embed this data in the database. I know that
I could hyperlink to files external to the database but don't want to do this
unless there are no other issues.

Thanks
