>I'll like to bind some data to some combobox on a form. The data came from SELECT - SQL made by SQLEXEC() from a remote VFP6 database. I want to know if it is better to keep the data in arrays or to keep them in cursors. The arrays or cursors will contain 2 or 3 fields ( 1 key, a description and maybe a code ). Is one more faster than the other? Is one take less memory than the other? etc.

Arrays take memory variable while cursors in essence do not. Cursors are stored using the temporary workfile space that VFP creates. As such, you can usually have more records in a cursor than rows in an array. Also, there is a distinct limit of 65000 elements to an array. With 3 columns, that gives you about 21600 rows. You may not exceed that, but you never know. < s >
