How to use array function?

I want to create a array with the data are in the table (one or more than one field).

By using function makearray or array, it can create the array with one record

e.g.

Local stringvar Array x := MakeArray ({CASES.ASSIGNTO});

ubound(x);

the result will be 1, means only one record is in the Array x.

Actually, I want to get all records of the field CASES.ASSIGNTO.
