Checking version via LOADLIB members
From ISPF, locate your ACR LOADLIB. Within the LOADLIB, there will be a member labeled U1#0000. If you browse this, paging over will display a product version number. This method is handy when verifying that the LOADLIB being utilized is correct. The example below shows the version as R90V3M00 (ACR 9.3).
