Lenze 940, access variable by index#

[Hooray4Automation]

Has anyone using this drive been able to access variable by index variables?

I can access V0 by its access number 100 using the @100. However, I am trying to use a dynamic indexer:

V0 = 20
indexer = 100
V1 = @indexer

this 'should' set the value of V1 = V0 = 20, but it sets V1 = indexer = 100.

Any suggestions for syntax?

Thanks
