Many THANK YOU's to those who responded! As usual with J, there's
often more than one way to accomplish something--in this case, 5
completely different ways that I can choose to add to my personal J
vocabulary.
The shortest was Skip Cave's response, but, Skip, I have a question
about how/why yours works. When I read the Vocabulary and NuVoc to
see how and why this works, I could not figure out how I would even
think to use "{" (catalogue) based on the information in those two
sources. The NuVoc definition/description is "Combines ITEMS from the
ATOMS inside a BOXED LIST to form a catalogue." My original list was
NOT boxed, so that description would automatically dismiss my example
from using "{". Can you please clarify why "{" can be used to box an
unboxed list?
And, by the way, in my programming, I like to do things small step by
small step so that I can be sure everything works correctly at each
point. My original goal in this case was to get the unboxed list
first boxed in the correct manner and then transpose it from a column
to a row. (It's part of stock market data from a particular vendor
which is out of "standard" order and format.) Three of the five
responses did both aspects (box and transpose) in a single
command--for which I am quite grateful. It showed me again how
amazing J is!
