I have been debugging an admin script all morning that executes 'activate policyset' commands, among others. Seemingly identical commands succeeded from the command line, but failed when run from a script, with "ANR2022E One or more paramters are missing". After checking everything else I removed the embedded tabs between the commands and their parameters, replacing them with spaces. That was the solution.
Is that in the book? With best wishes, Keith Arbogast Indiana University
