how to group the net objTypes?

I added local variable definitions in a let(() statement & don't get that error:
procedure(test_code()
let((net_db net vias shapes pins paths)
(axlSetFindFilter ?enabled "Nets" ?onButtons "Nets")
(axlSelect)
(net_db = (axlGetSelSet))
(net = car(net_db))
foreach(branch
(net->branches)
foreach(child
(branch->children)
when(((child->objType) == "via")
(vias = cons(child vias))
)
when(((child->objType) == "pin")
(pins = cons(child pins))
)
when(((child->objType) == "shape")
(shapes = cons(child shapes))
)
when(((child->objType) == "path")
(paths = cons(child paths))
)
)
)
)
)

David Hutchins,

Thanks for the reply.

I have run your code still i get errors

Skill > load("test.il")
t
Skill > test_code
Enter selection point

nil

Hello,

It's because you are appending to list of objects before declaring it in the following line.

shapes= cons(child, shapes)

Add this before foreach and code will work fine

pins=()
vias=()

shapes=()
paths=()

You can also declare pins=nil etc. 

Thanks,

Kirti,

Still it shows same error. Attached my code here.https://community.cadence.com/cfs-file/__key/communityserver-discussions-components-files/28/test_5F00_code.il

Note : I'm working in APD 16.6

Skill > load("test_code.il")

t

Skill > _testcode

Hello,

Its because vias , paths etc have been defined as local variables in function _testcode() using let as shown in excerpt below.
So they cannot be accessed from outside the function.

procedure( _testcode()

let( (net_db net vias pins shapes paths )

To access vias , paths from outside define the variables before procedure definition and remove from inside the function.
pins=()
vias=()
shapes=()
paths=()

procedure( _testcode()

let( (net_db net )

axlSetFindFilter(?enabled "Nets" ?onButtons "Nets")

Thanks,
Kirti
