<items>, <base>, <item1>, <item2>, <base>, <title>

[armsys]

After selecting one or multiple files, at the Address Bar, I type either of the following:
::text "<items>"
::text "<base>"
::text "<item1>"
::text "<item2>"
::text "<title>"
None produces the result as advertised.
Please correct me. Thanks.

Because you didn't read the help file...

UDC Open With only

<your variable names>

UDC Open With only

<your variable names>...

Actually I did read the manual. That's how I tried out the multiple XY variables.
And I don't understand what "UDC Open With only" is supposed to mean.
And I tried it out in UDC (CTRL+ALT+F9)...
And I tried out several hundred permutations and combinations in vain for a couple of hours before posting my question.
None succeeds.
Highend, would please guide me? Thanks.

As Highend said, "Open With"
So, <items> is only available in "Open With" section AND in the Application: field, you must supply a specific program similar to the help file:
"winzip32" -a UDCmade.zip <items>

In you screenshot above, you used "go to" instead of "Open With"
And even if it's Open With, the command ::text means nothing

But waht do you want to do?
In normal scripting other than UDC-Open With, just calling <selitems> or <curitem> is enough

binocular222,
Thanks for your clarification.
No, I didn't understand Highend's "Open With."
Now I realize he meant a Category in the UDC.
Now I realize the captioned XY variables work if and only if 2 conditions are satisifed:
1. Under Category: "Open With";
2. With a valid application such as WinRAR.
Yeah, they seem to work fine now per your clarified description.
Thanks a lot.
