Thank you, Richard Gaskin, for clarifying that.
What that does do is confirm my view that teaching children stuff such
as Scratch at school
has little or no value in the sense that it is NOT a programming language.
Teaching Scratch reminds me of Jas Pitman's Initial Teaching Alphabet:
intended to speed
up children's ability to read English all it succeeded in doing was in
slowing down their
learning the English writing system because they had already learnt an
"alphabet" with 45
letters, many of which, while resembling those in the English alphabet
were effectively false friends.
Every time anyone says "Let's use Scratch with young children" I start
sweating and having hot
flushes . . . and wonder why more is not being done to push Livecode and
programming IDEs in schools.

It leaves LiveCode where it's designed to be: among the world's most
useful scripting language IDEs.

I guess my writing was unclear.
I wasn't distinguishing between command-line tools and GUI tools, but
between IDEs in which *programming* is done through typing or via a
Of course LiveCode has a GUI for layout, as does XCode, Visual Basic,
Xojo, and many others.
And like those, the *programming* within the tool is done by typing.
This is a clear distinction from tools like Authorware, IconAuthor,
Scratch, and that whole category of VPLs, in which the *programming*
is done via a point-and-click GUI.
Of course no one's advocating that Kevin turn LC into a
command-line-only tool. Please.
But no matter how much time we spend doing layout in the GUI, the
objects we create are for the most part static. If we want them to do
anything we write code. And when we write code we do so by typing.

There's not much of a continuum there now. There wasn't much in
In HyperCard, the range of things you could code via its
point-and-click auto-scripting palette was limited to simple
navigation and little else.
Want to put the contents of one field into another? Add two numbers
and display the result? Read a file from disk? In Authorware and
other VPLs you can do those things via point-and-click, but all those
and nearly everything else we do require scripting in HyperCard, as it
Without scripting, LiveCode is only slightly more capable of making
interactive media than any drawing program. Which is to say close to
Responding to user actions with meaningful behavior in any scripting
language requires, well, scripting.
My point wasn't that we should turn LC into a command-line tool.
My point was merely reinforcing what Bill Appleton observed, and what
the market has demonstrated since: point-and-click *programming* can
sometimes lower cognitive load in early stages of learning, but at the
cost of inhibiting the range of complexity it can gracefully support
as one's skills grow.
While VPLs have for the most part come and gone, scripting has become
the dominant means of applications development in the 21st century.
Scratch is an undeniably valuable tool for young minds. But for
delivery of professional applications, even richer VPLs than Scratch,
like Authorware and IconAuthor, have waned while typing in scripting
languages has only continued to grow.
