It depends on whether or not the 61st has been created. If yes you'll get NO error. But you'll get an error if you try to access the 1st generation.

If there are 60 (or less) datasets cataloged for the generation data group, then an attempt to access the 61st generation (i.e relative address -60) will result in the JCL error message

"IM256696 IEF212I jobname stepname ddname - DATA SET NOT FOUND".

However, if you access the generation directly by it's explicit name, i.e.,
'HLQ.DATASET.GDG.G0001V00', then you will not have a problem.

An attempt to use the relative index beyond the range of the LIMIT will result in "DATA SET NOT FOUND". Using the explicit name (i.e. the "GooVoo") will work just fine.
