Using MSSQL 7 scripts with MSSQL 6.5

Hi,
I’ve SQL scripts for table creation written for MSSQL 7. The scripts contain all the Primary/Foreign key definations and creats all the tables needed. Now I’m stuck up with MSSQL 6.5, I want to use my Ver 7 scripts but they give error when I run them through enterprise manager.
Is there a way I can convert the scripts? I don’t have access to MSSQL 7 but only MSSQL 6.5 . It would save me a lot of time creating tables. So I would definatly like to use these scripts if I can.
Again, the scripts only create tables and define the keys. Any suggestions?
