Folks:
I’m looking at Jan Schenkel’s posting on the “Power of Merge”.
I can’t make any of the examples work.
Obviously, there is some code or some very basic thing that everybody (but me)
knows, but ??
Please illuminate me. I see the placeholder in some of the lessons. The
dictionary is no
Thanks everyone. Templates makes sense.
Just for grins, perhaps the dictionary entry could be enhanced with Jacque’s
example.
It makes sense to me now.

Kee,
I can spend hours on why merge is useful and underappreciated but I will
boil it down to one use case only: templates.
Merge is crucial if you're assembling some textual template that is not
LiveCode but want to generate parts of it in LiveCode. For example, the

merge([[ 1 + 2 ]] = 3) produces a script error,
this should read merge("[[ 1 + 2 ]] = 3").
Merge is the one and only function

What is it that merge can do that a put cannot do?
For me, it's convenience,
Folks,
I’ve been following this discussion, barely. I don’t use merge, but when I need
to form a command from several variables, I create the command as a text string
and use do to execute it.
So, when I look it up in the dictionary, I see a fairly simplistic description
with nothing
There's some overlap, but merge has (at least) one feature that put
doesn't: the ability to run code within its statement. A simple example:
put merge("The coin came up .")
The equivalent might be:
put "The coin came up" && item random(2) of "heads,tails" & "."
But consider this:
I’m confused. Can someone explain why merge function exists when the put
function works just as well?
merge( [[ 1 + 2 ]] = 3)
vs
put 1 + 2 && “= 3”
What is it that merge can do that a put cannot do? Just asking because I don’t
want LiveCode to end up like Perl where there are so many
