Hi Folks:

Just a quick note to thank all of you for your suggestions on resolving my fatal database error 317.
And also to update y'all on just what happened.

In trying to save myself some post-processing work, I had added a polarity sign (text) to the silkscreen
layer of a decal for an electrolytic cap.  Turns out that at some point when I had ascii'd out to verify
the PCB database, PADs couldn't handle the plus sign (text) attached to the decal's silkscreen layer and
created what I'll call a detached decal record.  This snowballed into some other nasty corruption which in
subsequent import/export cycles implicated other sections of the database.  At any any rate, here's the
sequence of remedies, compiled from all the best ideas y'all gave me.

1)    Examined the last known good ascii out file compared to the first known corrupted file to find the
bad part  decal record wreaking havoc.

2)    Corrected the cap decal  in the library to remove the plus sign.  Actually a polarity sign made with
two line segments may have been ok in hindsight.

3)    Exported from the final layout, the parts (layout), pcb parameters, lines (board outline), and
miscellaneous sections.

4)    Imported ascii from last step forcing PADs to use new decals.

5)    Net list compared PCB from step 4 with new ascii from Viewdraw.

6)    Imported ECO from step 5 to PCB created in step 4.

7)    Did an Import/Export cycle on  PCB from step 6 to ensure database integrity.

Now the card's good to go

Thanks again for all the help.
