Hello everyone:

Sometimes, vfp debugger stops at some invisible breakpoints.

There is a test program from Mr. Leonid Lepin (or Mr. meligo):

     *PROC testbreakpoint

     SET STEP OFF
     SET ECHO OFF
     SET DEBUG OFF
     SET ESCAPE OFF
     SET TALK OFF
     SET SAFETY OFF

     _SCREEN.VISIBLE=.T.
     _SCREEN.WINDOWSTATE=2

     ? 'Phantom BreakPoint'
     INSERT INTO tttt (f0,f1,f2,f3,f4,f5) VALUES (CHRTRAN(somestring,'\','/'),1,2,3,4,5)

     RETURN

     * END OF PROC TESTBREAKPOINT.

We can set a breakpoint at the line:
INSERT INTO tttt (f0,f1,f2,f3,f4,f5) VALUES (CHRTRAN(somestring,'\','/'),1,2,3,4,5)

But when we run the program, the debugger stops at the line:
? 'Phantom BreakPoint'
