Judy, et al:
If-Thens are readily comprehensible by non/novice-programmers.
And by extension, switch statements are not. [?]
When I gave you this point in an earlier post, I was really conceding
that the syntax of a switch statement does not flow in the same
English-like fashion of "ifs" in xTalk.
Maybe I've been at it too long to see the forest for the trees; but I
truly don't see what is so hard to comprehend about the switch concept.
One identifies a switch value and specifies different logic paths to
follow depending on the value of the switch.
on menuPick thePick
switch thePick
case "Cut"
...
break
case "Copy"
...
break
case "Paste"
...
break
[etc.]
default
answer warning quote&thePick"e&&"is not
supported!"
end switch
end menuPick
It can be explained in terms of if/then/else--which you find easily
comprehended--; so when it's explained in that context it should be
readily understood....no?
Again, I'll grant you that there is more to switches than that simple
example shows; but the basic concept is not that difficult to
understand or explain (to me; but I have to defer to your classroom
experience, as unintuitive as it is to moi).
