Dictionary Database Structure DICTOBL Fields
NULL-VALUE the ASCII value used by DDL when producing FUP source output
for an alternate key.
NULL-VALUE-OBJECT if the null value is defined by a constant, contains the
object number of the constant; otherwise, it is 0.
SPI-NULL-VALUE contains a user-specified SPI null value used by SPI to process
token maps.
SPI-NULL-VALUE-OBJECT if the SPI null value is defined by a constant, contains
the object number of the constant; otherwise, it is 0.
NULL-VALUE-SPECIFIED contains the ASCII character Y (yes) to indicate this
item has a null value or N (no) to indicate it does not. The default for this field is N.
SPI-NULL-VALUE-SPECIFIED contains the ASCII character Y (yes) to indicate a
SPI null value was explicitly specified for this object or N (no) to indicate it was not.
The default for this field is N.
UPSHIFT contains the ASCII character Y (yes) to indicate this data item is to be
upshifted or N (no) to indicate it is not to be upshifted.
Only an elementary item can be upshifted. The field must be declared as
alphabetic or alphanumeric. The default for this field is N.
USER-DEFINED-FILLER contains the ASCII character Y (yes) to indicate this field
is a user-defined FILLER field or N (no) to indicate it is not. The default for this field
is N.
PADDED-FILLER contains the ASCII character Y (yes) to indicate that an SQL
VARCHAR element has an odd byte length and has an OCCURS clause
associated with it; contains N (no) to indicate that the element does not. The
default for this field is N.
GROUP-COMP for group items; contains the ASCII character Y (yes) to indicate
the group is defined as computational or N (no) to indicate it is not. All elementary
items within a group defined as computational are treated as though they were
individually defined as computational. The default for this field is N.
SOURCE-DEF-FLAG contains the ASCII character Y (yes) to indicate this item is
defined with TYPE * or TYPE def-name or N (no) to indicate it is not. The default
for this field is N.
NOVALUE contains the ASCII character Y (yes) or N (no) to indicate whether this
item has the NOVALUE attribute. NOVALUE suppresses any VALUE IS clause in a
referenced definition. NOVALUE can be specified only for a field or group definition
defined with a TYPE clause. The default for this field is N.
TACL-INHERITED contains the ASCII character Y (yes) to indicate the TACL type
was inherited from a definition or N (no) to indicate the type was explicitly
specified.
