timer checked. all outcomes are possible

>I wouldn’t trust his LM358 to give a reasonable output with all 3 pins being held to the same potential as its negative supply
it's not a 741. ground is fine, it's inputs near V+ that are problematic. besides, offset voltage is almost never exactly 0

learn the keyboard shortcuts. in the library editor, down down enter name tab pinnum enter
if you already have the pinouts in a machine-readable table of some sort, you can export a symbol and code up a quick awk/perl/sed/powershell/BASIC/batch command script to convert them into
>X (pin_name) (pin_num) 0 (pin_num*100) 200 R 50 50 1 1 I
format, whose output you plug back into the exported symbol's DRAW section and then reimport, moving and rotating pins as desired. great for FPGAs
