Brian,

the text of the views is stored in a LONG field (desc all_views). By default, you do not see the whole content of a LONG field in SQL*Plus but only the first 80 characters.

You have to set the LONG parameter in SQL*Plus by:

        set long n

where n stands for the number characters to be displayed.

And, do not forget to set the pagesize to more than 24 lines...

Hope that helps.
