I'm back to CSLS after a long break. Does anyone know the purpose of the pipe/vertical bar | character? Is this unique to UCBlogo? I've played around with it but I can't find a description anywhere.

EXAMPLE:
to sayrow :row :letter
type item :row thing :letter
type "| |
end

make "b [|*****| |* *| |* *| |**** | |* *| |* *| |*****|]

With vertical bars, you can use characters in a string that would be considered special characters otherwise

PR "HELLO WORLD
HELLO
I don't know how to WORLD
PR "|HELLO WORLD| => HELLO WORLD

Some Logos, like Terrapin Logo, also use vertical bars to preserve case.

PR "Hello => HELLO
PR "|Hello| => Hello
MAKE "A [a |b| c]
PR :A
[A b C]
