Creating multiple directories simultaneously
I could have sworn that I saw a method of creating several directories,
actually a parent direct and several sub-directories simultaneously;
however, I cannot fine the documentation any longer.
Assume I want to create a directory: FOO with three directories under
it, foo-1, foo-2 and foo-3. I tried: mkdir -p foo {foo-1, foo-2, foo-3}
and several other variants and they all failed. I could easily write a
simple script to accomplish it; however, I thought I could do it
directly from the command line.

Almost.
$ mkdir -p FOO/{foo-1,foo-2,foo-3}

mkdirhier dirtest/dir1 dirtest/dir2 dirtest/dir3

Or, for even less typing:
$ mkdir -p FOO/foo-{1,2,3}
Understand how this works, however, so you won't need to look it up
again, but can apply it yourself in whatever variation is needed. It's
called brace expansion. Here's the first hit that comes up in Google,
which describes it fairly well:
http://snap.nlc.dcccd.edu/reference/bash1/features_11.html
This page is about the bash shell, but brace expansion works the same
way in tcsh. It is NOT supported in tne Bourne shell.

For extra credit, and to test your understanding, see if you can explain
how the following work:
$ mkdir -p FOO/{foo-,bar-}{1,2,3}
$ cp foo{,.bak}
Others might have some even more complicated examples worth exploring.
(It sucks, btw, that most of what Google finds pertaining to brace
expansion is about bash, when the feature was actually introduced by
csh.)

Maybe I am doing this wrong; however, I had to use the -R flag with
'cp' to make it work. I also assume you meant FOO and not foo
unless I am completely misunderstanding this exercise.
cp -R FOO{,.bak}
FOO - FOO.bak/FOO
FOO/foo-1 - FOO.bak/FOO/foo-1
FOO/foo-2 - FOO.bak/FOO/foo-2
FOO/foo-3 - FOO.bak/FOO/foo-3
FOO/bar-1 - FOO.bak/FOO/bar-1
FOO/bar-2 - FOO.bak/FOO/bar-2
FOO/bar-3 - FOO.bak/FOO/bar-3

Sorry, pedagogical error. I didn't intend that to operate on the
results of any of the other examples. I probably should have chosen
something other than 'foo' in order to avoid that misunderstanding.
The point was simply to explore what happens when one of the terms
inside the braces is an empty string.
