• use HPAUTOCONT variable judiciously. This is better:
continue
command
if hpcierr > 0 then
echo something…
return -- or -- escape
endif …
• RETURN vs. ESCAPE
• :return goes back ONE level
• :escape goes back to the CI level in a session, to an
active CONTINUE, or can abort a job
• HPCIERRMSG - variable contains the error text for the value of
CIERROR JCW / variable
• :ERRCLEAR - sets HPCIERR, CIERROR, HPFSERR,
HPCIERRCOL variables to zero
