The editor switches to this mode, when the call is corrupted. You cannot edit this code. Between the Call / End Call you see how the parameters are passed in MC7 code. The BLD instructions are there to help the editor how to build the STL code with the FB Call from the MC7 code. But there is not official documentation about this.

	Regards, Jacek What is confusing you is the fact that you never see a number but always its digit representation. So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded.

	If you like the comment, rate it (right top) or thank it (left bottom). One who says he can & one who says he can't, are both correct-Confusius. Automation- C2C, Management Sachin Patke, India.
