Hi !

I know I am being picky, but since You posted to the "sms & vsam" and vsam forum i feel You should be warned about the differences between the reuse parameter for a tso allocation and the reuse parameter for a cluster definition !

in the first case it is an addition parameter used to avoid allocation errors

in the second case You must consider carefully it' s use since it implies that for an "open output" operation the vsam cluster will be reset to an empty status
