thanks Mark
i'm in the process of trying your solution! - i am still wondering if there
is a solution which does not involve tampering with the library as having
"portable" SSQLs seems like a pretty fundamental requirement to me

Not sure if this is the redef problem you are refering to but I tackled
a redef problem a ways back. Check it out here...

thanks Chris
i want to create some objects in my library that contain SSQL structures
- so i might have a widget class that contains an SSQL stock & an SSQL
price - the widget object would be used in the higher level appication,
requiring knowledge of the SSQL definitions, hence the redefinition
problem - can i do this?
