;VERSION 5A COMMENT
;
; THIS WAS EDIT 436 FOR VERSION 5.
;
;SYMPTOM
;
; DBINFO DOES NOT RECOGNIZE A DISPLAY REQUEST WHOSE PAGE
; RANGE LIES OUTSIDE THE AREA SPECIFIED. WHEN THIS OCCURS
; DBINFO RETURNS THE MESSAGE "?INFDAF DATA BASE ACCESS
; FAILURE -- IS DBMS PROBLEM IF IT RECURS."
;
;DIAGNOSIS
;
; INAPPROPRIATE DBINFO ERROR MESSAGE. (UNFORTUNATELY NO
; NEW ERROR MESSAGES CAN BE INTERPOLATED INTO THE DBMS V5
; .REL LIBRARIES.)
;
;CURE
;
;
; SELECT AN ERROR MESSAGE WHICH WILL CAUSE THE USER TO
; LOOK IN THE PROPER PLACE FOR REFERENCE MATERIAL, I.E.
; IN HIS SCHEMA FILE. INSTALL EDIT 527 TO GIVE DBINFO'S
; ?INFSAF MESSAGE IN THIS CASE.
;
;
;
;NOTE ***** THIS EDIT APPLIES TO DBMS-10 V5A ONLY, AND TO DBINFO ONLY
; SEE EDIT 526 FOR DBMS-20 V5A.
