I have written a simple program in the flexpendant.The program is that(it is very simple):  
MODULE MainModule  
CONST robtarget Target\_10:[,,,,];  
CONST robtarget Target\_10:[,,,,];  
PROC main()  
MoveL Target\_10,v1000,fine,tool0;  
MoveL Target\_20,v1000,fine,tool0;  
ENDPROC  
ENDMODULE

When I run ,the result is:  
Failed to start.  
Missing at least one task program pointer.

But when I simulate the program in the robotstudio,it works .

So ,I do not know how ?

Did you set “program pointer - PP” to main routine before starting the program?  
(Program Editor \> Debug \> PP to Main)
