IBM Informix Load and Insert with multiple files

Hi ,

Can you guys please help as I have list of files xaa, xab, xac.........xza for eg in which to perform load the 1st (xaa) and insert into table, then only proceed for the 2nd , 3rd and so forth.

In other words, before 1st one finished, 2nd one shall not load and insert to table, and so forth.

Regards,
