Hi
As others already said:
Options missing='0'; is for PRINTED output like LISTING, PDF, HTML or the like.
This is something you rarely create with DIS. The values are not set to 0 in the tables - nor is this a format showing missings as '0'. As the output of your DIS jobs is normally a table, Options missing='something' has no effect.
Not sure what you've seen in EG. But the TABLES sure didn't show a '0' either.
