Hello all,
When I define a variable as a variable that is a concatenation of
string arrays, I get strange data that suggest an initialisation bug.
As an example, initialise two arrays and concatenate those into the
variable pre_list. When we print pre_list, we'll get the expected
value, namely {"a", "b", "c", "d"}. However, it goes wrong when we
define a new variable final_list as pre_list. The can be shown with
the following code:
can var/all
let list1 = {"a", "b"}
let list2 = {"c", "d"}
let mylists = {"list1", "list2"}
let pre_list = XCat( list1, list2 )
let final_list = pre_list
list final_list
The result is {6.699-316, 6.699-316, 6.699-316, 6.699-316} or a similar
number (different answers on different machines, or between pyferret and
ferret).
With numbers instead of strings, there is no problem. Also, without the
concatenation -- let a = {"a", "b"}; let b = a -- I get the expected
result. The problem appears to be a combination of concatenating
string arrays with an extra assignment of the end result.
I am using Ferret 6.96.
