** Array subscript <value> is out of range. (26)
** Array subscript 0 is out of range. (26)
Code to reproduce the problem:
DEFINE TEMP-TABLE test
FIELD logfield AS LOGICAL EXTENT 3.
CREATE test.
IF TEMP-TABLE test:DEFAULT-BUFFER-HANDLE:BUFFER-FIELD("logfield"):BUFFER-VALUE() = NO THEN
DISPLAY "no".

DISPLAY "yes".
FACT(s) (Environment):
All Supported Operating Systems

CAUSE:
Bug# OE00197766
CAUSE:
The BUFFER-VALUE attribute of a BUFFER-FIELD allows the usage of parenthesis when dealing with array fields to specify which element you are addressing. When left blank this should return an error anyway, but it shouldn't crash.
FIX:
Indicate which array element you are referencing in the parenthesis of the BUFFER-VALUE attribute:
e.g. :BUFFER-FIELD("logfield"):BUFFER-VALUE(1)
