What does the 'also documented' sentence mean. How would a non-existant
label appear before the GO in a paragraph.
Regarding paragraphs: Do they behave like procs whereby you can
Yes.
On this topic, does the proc statement
[PQ.LIB OTHER.PROC] 100
work on U2's. Just wondering.

This is just plain, simple bad programming. In a paragraph, jumping to an
undefined label terminates the paragraph. It is totally unsafe to use this
as a nifty way to end because someone might later add the label for some
other meaning in the same paragraph.
In a Basic program, as one responder

this works. Is OUT some kinda built-in label?
Don't think so, it seems like any undefined label will abort from the
paragraph.
