It's possible but you need to know a struture of your Dos database Dbase, Texte file ??? Export into a text file your data with separation on each record with coma ; Some dos Database have export option to text file if you don't have this option is really hard you need to use Open # do a search Open in the Help of Access something exemple is include.
Maybe you can use the option of import in Access 2002 if the Type of your DOS database is include in the option.
like this.
MyFields1;MyFields2;MyFields3
MyFields1;MyFields2;MyFields3
MyFields1;MyFields2;MyFields3
MyFields1;MyFields2;MyFields3
MyFields1;MyFields2;MyFields3
etc...
After that you need to import the record (text file_ with delimited text, set to ";" for separator
After, set the structure of each fields in edit mode table.
but you can import text in existing table but each record need to match with the structure of your table.
Good Luck !
