Have a DO CASE statement. Execution is falling into

"CASE EMPTY(paytemp.PRIN_PMT) AND EMPTY(paytemp.INT_PMT)"

Underneath the CASE there is an ASSERT .F., IF structure and various comments. The ASSERT is the first thing. In the debugger I can see that paytemp.INT_PMT = 2. Thought maybe I needed to move off the row so I SKIP, SKIP -1, before the DOCASE. I am still in the CASE yet paytemp.INT_PMT = 2.

Any ideas why the CASE is evaluating to .T.?
