UDC / script exit
• EOF -- real EOF for scripts, a row of asterisks (starting in
column 1) for UDCs
• :BYE, :EOJ, :EXIT -- terminate the CI too, to use BYE or EOJ
must be the root CI
• :RETURN -- useful for entry point exit, error handling, help
text - jumps back one call level
• :ESCAPE -- useful to jump all the back to the CI, or an
active :CONTINUE. In a job without a :CONTINUE,
:escape terminates the job. Sessions are not terminated by
:escape. Can optionally set CIERROR and HPCIERR
variables to an error number
