<p class="MsoNormal">Hi Hernando,<o:p></o:p></p>
<div>
<p class="MsoNormal"><span class="apple-tab-span"> </span>Perhaps runCommand should return a value but it doesn’t. The reasoning there was that the argument to runCommand could be anything, including several commands separated by semi-colons, so
in some cases it’s confusing what the return value should be. In any case that ship has sailed and you have to do something else to get the value. In most cases it calling the underlying function that performs the command and using it’s return value, but
looking at the code that implements the “measure center” command I can see that it doesn’t return anything either.<o:p></o:p></p>

<p class="MsoNormal"><span class="apple-tab-span"> </span>So in the particular case of the example you provided, I can see two options for getting the value:<o:p></o:p></p>
