The Swap User Profile command allows a swap to a user profile and runs a
command under the new user profile. You must have *USE authority to the new
user profile, but the authority may be adopted. When the command completes
(either normally or abnormally), a special 'scope' program is used to ensure a
swap back occurs to the original profile. Among other uses, SWPUSRPRF allows a
means of adopting when using IFS objects.
