In Toad 10.x, the number of tasks that a script included could be seen (eg., Task 3 of 7) during Execute as a script ( F5).
This is very helpful when there are long scripts. However, in version 11.0 it always says Task 1 of 1.
It happens when statements lead with EXEC commands are run as as script. For example:
...where a1, a2, a3 are procedures
This happens in Toad for Oracle Editor, as well as, Quest Script Runner.
Waiting for fix in a future version of Toad for Oracle.
