H JUMP v3.0, SYSTEM_MANAGEMENT, Become a different user exactly or in part  H JUMP is a  program  which  allows  selected  users (Systems Programmers,H Operators and specifically authorised users) to change elements of theirH process to those of another user, or to become *exactly* the target userH in  a pseudo-terminal.  Limitations are placed on Operators: they cannotH target users who have more than a certain set of privileges unless  they% are specifically authorised to do so.   H All users except Systems  Programmers  are  validated against an  accessH list  file  to determine any specific access to be granted or denied  in5 addition to any default access (e.g.  for Operators).   H For non-exact jumps, items which are changed to those of the target user are:  I   Username (Systems Programmers only, using the SETUSER or ALL qualifier) 2   UIC, Default Directory, Default Disk, LNM$GROUP.0   Privileges and process rights are NOT changed.   To install JUMP:  D   1. Re-link JUMP (NO Traceback) as directed in the build procedure.M   2. Define EXECUTIVE mode SYSTEM table logical names as required (see help). 3   3. If required, create the JUMP_ACCESS rights ID. F   4. If required, grant the JUMP_ACCESS rights ID to authorised users.K   5. If required, create/edit the user access data file (see example file). I   6. INSTALL JUMP with privileges: CMEXEC, CMKRNL, DETACH, SYSNAM, SYSPRV A   7. Define a foreign command: $ JUMP :== $device:[directory]JUMP    8.
