If someone wants to use this technique of a job searching its own $STDLIST
for a particular string, like "*W*" for a PowerHouse warning, there is [at
least] one caveat: the command will always find one occurrence of the
specified string, in the command that mandates the search!  One way of
avoiding this would be to have the search in a command file external to the
job itself.  MPEX does help solve this problem by offering the variable,
MPEXPRINTLINESFOUND that can be interrogated:

:IF MPEXPRINTLINESFOUND > 1 THEN  {not > 0 }
:   do something
:ENDIF

Jobs that have to check whether QUIZ found records or not would do better
to check the resulting subfile with MPE/iX FINFO:

:IF FINFO ("subfile","EXISTS") THEN
:    IF FINFO ("subfile","EOF) > 0 THEN
:        TELLOP IT'S OK
:    ELSE
:        TELLOP NO RECORDS FOUND
:    ENDIF
:ELSE
:    TELLOP NO SUBFILE PRODUCED AT ALL
:ENDIF
