I need to step programs and see which line is executed. It works ok if the program was loaded to task slot via RT Toolbox 3 using commands like: LINENO and LINERD.

But I also need to swap and upload programs via R3. When I try to do it I get this error:

OUT:1;1;PRGLOAD=PART2.MB6

IN:QeR602000000

Error does not show on a error list in RTToolbox so I have no idea what does it mean. Do you have a manual with error codes?
