Assigned or Not Assigned, That's the Question

armsys · Post by **armsys** » Wed Feb 02, 2011 1:23 pm

In the following code, Assigned> fails to tell the truth: whether the variable has been assigned:

Let>i=1
Let>j=1
Assinged>Item%i%_%j%,x
Let>Item%i%_%j%=XXX
Assinged>Item%i%_%j%,y

Assigned doesn't work with complex-embedded/array-type variables. Just simple ones. Sorry.

Check spelling
Assigned rather than Assinged

What are you trying to do?

Marcus,
All I need is your confirmation so that I can stop torturing my brain. Of course, there're always alternatives to vet if a complex/array-type variable is assigned with a value. Of course, it would be nice if Assigned> command can support complex/array-type variables in the future releases.
Is it important? Definitely. We don't always know the exact number of array elements. And we don't always know if an array element has been assigned with a value.
Thanks.

Jerry,
That's the same question I wish to ask. Yes, it was a misspelling. Probably I drowsed off while typing the command. Amazingly, the MS Debugger didn't complain. Even with "Assigned>," the results are the same. Thanks for pointing out my typo.
