ASK dialog box

[Roland Huettmann]

Dear Randy

Maybe the obvious is sometimes not so obvious when starting. And even
following the discussions on this board, with all those acronyms, many
users - also me - are sometimes lost guessing around what this or that
could mean.

It is very simple in LiveCode catching the Ask box:

The code snipped goes like this:

The lengthy form writing the script:
...
if it is empty then -- it is empty = Cancel
  exit to top -- or whatever you like
else
 doSomethingElse -- it is not empty = OK, then do what you want
end if
...

Here we assume that there are only these two buttons: "Cancel" and "OK"
