Hello,
I am working with Queues in FB5. The Queues work fine when I give a static name to the queue. However, when I need to define queue’s names which contain the value of a variable (namequeue_%number%), it seems that all of the queues that are related with namequeue_% number % share the same memory address. If I have for example namequeue_1, namequeue_2 (where 1 and 2 are values of %number%), when I log the content of these queues they both have the same content (the content of the last one).
When a queue is defined in PB5, in the build log we can see “Queue [namequeue_%number%] defined.” Maybe the definition should be with the value of the variable instead of using the name of the variable. It seems that the definition should be “Queue [namequeue_1] defined”, so that each instance can have their one memory address.
You can try to reproduce this issue using the following pseudo code:
For [number] = 1 To 2 Step 1
Define queue [namequeue_%number%]
Clear Queue [namequeue_%number%]
If [%number%] =1
Push items on Queue [namequeue_%number%] (Push a, b, c)
Else
Push items on Queue [namequeue_%number%] (Push x, y, z)
For [number] = 1 To 2 Step 1
Log items on Queue [namequeue_%number%]
The log will show:
namequeue_1 = x, y, z (it should be namequeue_1 = a, b, c)
namequeue_2 = x, y, z
Please let me know your comments about this issue.
Thanks.
Rosalva.
