Re: Possible bug (?) with lists in 6.2.0

Hi Brian,

you don't have to use (/test_data/) in the ListPush call just test_data:

test_data = ispan(0,10,1)
test_list = NewList("fifo")
ListPush(test_list, test_data)
print(test_list)

test_list has only one dimension containing the list variable test_data.
Using ListPop
with fifo list type will return the first list variable if you pushed
more list variables to
test_list.

Hope this will help,
Karin
