Visual FoxPro 9:  Logical changes after printing

I have a simple table with .T./.F. logical fields used to control which programs run.  When I set several fields to .T. so that the respecive programs will run, then open the debugger to "watch" the status of the fields during processing, I found that, when a REPORT FORM form_name command is executed, the field value (in memory) changes to .F.  I've never seen this happen before.  For example, the table value shown in the watch window is SUBMIT.PROGRAM1=.T.  After the REPORT FORM command executes, the value in the watch window becomes SUBMIT.PROGRAM1=.F.

I also found that, if I open the Data Session window and browse my control table while processing is on hold in the debugger, the actual field value remains .T., and when I return to the debugger, the field value (in memory) has returned to .T.

Has anyone seen this behavior before?  How can I correct this?

Did you also check EOF("SUBMIT") in debugger?

When you reach the EOF in DBF all logical fields will swap to .F.

You were correct.  Thank you so much!  It didn't occur to me that the pointer might be at the bottom of the affected table.  I found a GO TOP was missing after the last print instruction.  It somehow was deleted during some editing a few months back.

Thanks again.
