I am an Old PLC Programmer, and I love symbolic addressing. It's much easier to start typing the symbol name and picking it from a list box instead of remembering the address.

We've developed a standard somewhat different that yours, our symbols are named using modified Hungarian Notation for example:
PXClampCyl2-3Advanced. We prefer this to having Underscores.

I guess I'm one of the old farts now too. I can't imagine doing a program without symbols. I think the problem is you have seen programs written by people not familar with the AB programming platform or not properly trained. Symbols have been essential since the old Dos ICOM days.
