There are certain scenarios where the "Use (Storage)" code block is required and other scenarios where it is not necessary. For example, a new shared collection is initialized and the collection is about to be modified.

// Initialize new shared collection Use (Storage)    Storage.test:=New shared collection End use

There are two ways to modify the existing shared collection or shared object: member functions or assignment. In this example, if the shared collection is modified using a member function like collection.push, only the Use (Storage.test) code block is required as shown below:

// Use (Storage) is not required since push method directly modifies the collection Use (Storage.test)    Storage.test.push(1) End use

If the shared collection/object is reassigned to a new value, both Use (Storage) and Use (Storage.test) are required.

// Both use code blocks are required when assigning new values Use (Storage)    Use (Storage.test)       Storage.test:=New shared collection    End use End use

Otherwise, using only Use (Storage.test) on reassignment will result in an error.

// Error Use (Storage.test)    Storage.test:=New shared collection End use
