Eric,

This is my favorite way to talk to objects...

  put the long name of control x into thisobject

you can "do" everything "safely" now to your thisobject...

  set the rect of this object to arect

except assuming thisobject is a field

  delete line 2 of thisobject

or worse

  put empty into thisfield

you are then working on the variable, emptying it's valuable content...
so this requires the clever dynamic script trick i love so much:

  do "put empty into" && thisfield

[see the "do" command in the revdocs ;)]

Test it a bit... to avoid lengthy checking of what went wrong
try first to 
  get <command string> -- eg "get the time"
  do it

If you breakpoint after the "get", you can easily see the command that is
going to be fed to the compiler... eh, sorry, interpreter... Dynamic scripts
are slower - but not that slow...

- wrappers a la Taoo - delicious with a great IDE like Rev...

This lends itself to wrappers anytime! How to build your own libraries? ...

do something to this library context object...
so in brief, we modularize and normalize (reduce) handlers to their minimum
such that they are strictly <verb><object> <params>. Here for a field class
library we have a great example... <verb><field> with some exceptions that
require dynamic scripting.

And it's the way TAOO or many other libraries work too - using both the
basic long name reference and the dynamic execution. I know some expensive
tools that dont do this and they suffer badly from it! Remember the key is
to use the long name. It avoids all confusions.

on ClearFields objs
  repeat for each line thisobj in objs
   if exists(thisobj)
   then do "put empty into" && thisobj
  end repeat
end ClearFields

For more examples, try my geometry manager GIM.rev on MonsieurX.com (easy to
'find').

Since the long name contains the full path to any control, you can't miss
working on the right field or tripping on a changed-name field!!!

Remember also that the long ID of a control is less likely to change within
a stack than a long name. That's assuming you dont replicate this one to
other stacks where names dont change but IDs do! - IDs have their short
comings too...

And so with that concludes this little trick of TAOO wrapping and Xtalk
object addressing in the single, plural form ;)

More about this very soon (ed.)

cheerios
