Freeze all layers except pick
Here you go. Its LIT command [= Layer Isolate as to Thaw/Freeze condition only] is similar to AutoCAD's LAYISO with some important differences beyond just that it Freezes rather than turns Off the Layer(s) on which nothing was selected [see the related Tip referred to]. And it has the corresponding LUT command that operates similarly to LAYUNISO with those same differences. [You can pick things on more than one Layer if you want -- if you do, one of those Layers will become current, though you may not be able to control which one.]
EDIT: Downloading it at the linked site is currently not working. See Message 23 here.

.... Indeed the lisp [at Message 1]works with FF in command line, and thank you for that. What’s the point of this lisp file if it does what LAYFRZ command in AC does? .... I was expecting to click on an object in my drawing press Enter and everything else to freeze, but the one I highlighted. It freezes the object I click on which doesn’t do any good... for me.
Go back and re-read the Message itself at Message 1. They didn't attach a routine that did what they wanted, but one that did the opposite, as an example of something they wanted the reverse of. Mine in Message 2 was made to do exactly what you were expecting, except for letting you pick things on more than one Layer to remain thawed, which is the thaw/freeze equivalent of the way LAYISO works for the off/on condition.
[LAYFRZ probably didn't exist in AutoCAD yet at the time that code attached in Message 1 was written, so there was indeed a point to it.]

Please tell me how to have your lisp loaded all the time in my AC. Every time I quit the prog the lisp gets unloaded. What do I have to do? Thank you.
Open up a plain-text editor such as Notepad. In it, put this line:
(load "LayerIsolateThawFreeze")
OR this line:
(autoload "LayerIsolateThawFreeze" '("LIT" "LUT"))
Save that to a file called acaddoc.lsp, in any logical-looking folder [most likely one with "support" in the name] that is in the Support File Search Path list, in the Files tab, in the OPTIONS command dialog box.
Whatever is in a file of that name [you can add more lines with other routines you want loaded] gets done in every drawing you open, new or existing. If you use the first one [the (load) function], it will be loaded outright, and the commands in it just plain defined. If you use the second [the (autoload) function], it will have its command names "flagged" to be available, but the code itself won't get loaded unless and until you call for one of those commands. The latter approach can save some time in opening up drawings if you eventually have a lot of such things listed in the acaddoc.lsp file.
