There are eleven ways to fill in the fields:

1. with random values. More...
2. with the values from the list specified by the user. More...
3. with the values from the column of another database table specified by the user. More...
4. with the values from the file specified by the user (one value per line). More...
.
5. with the incremental values starting from the specified value. More...
6. with the values from the Values Library. More...
7. ignore field (uses for auto incremental fields such as identity or counter).
   
8. with random values according to the mask. More...
9. with result of the SQL statement execution. More...
10. with results of the expression based on another column(s). More...
11. Group item. You can not set or change this fill method directly.

As to lists of values and lists in a file (including Values Library), the program allows you to use its special "use sequential values from the list" mode when data will be taken from the list not randomly, but sequentially in a loop.
Also, the program allows to interpret the value of the list as a mask. The "Use list items as a mask" checkbox is used to enable this mode. This option supports for "list", list "from file", "Values Library" and "From Table" fill methods.
