Bill,
thanks for that but i dont think i will be adding to field 11, too many
dict items.
I could always set up alternative dictionarys but would rather not have to
do this.

Dictionaries do not control the contents of data files, so there's no real
way to to determine if an attribute contains multi-values or not.
Generally, MV databases are multi-value self aware. This does not apply
to
UniData (except for conversion codes). By this I mean if you "LIST
SOMEFILE
SOMEFIELD" you will get output that will look like:
SOMEFILE.. SOMEFIELD.
1 14016
14017
14018
2 14019
...where records in the file have multi-values in the SOMEFIELD attribute.
If you place a conversion code, like "D2/", in attribute 7 or 8 of an "A"
or
"S" type dictionary, the conversion will execute on each value:
SOMEFILE.. SOMEFIELD.
1 05/16/2006
05/17/2006
05/18/2006
2 05/19/2006
For reasons I won't get into here, conversion codes are normally placed
into
attribute 7 of an "A" or "S" type dictionary (attribute 3 of "D" or
"I"/"V"
type dictionaries).
"D" or "I"/"V" type dictionaries do contain a loose definition of whether
an
attribute is multi-value or not. Attribute 6 of this type of dictionary
contains that information. In UniData, in order for multi-value
processing
to occur in UniQuery, this attribute __MUST__ be defined as multi-valued.
Still, however, the database does not require it.
The use of attribute 4 and 5 of an "A" or "S" type dictionary defines a
multi-value association. For instance, if an A/P invoice record exists it
usually has two attributes defined as G/L account#s and associated
amounts.
In this case you could define an association in these types of
dictionaries
as "D;.." and "C;..", where ".." is the appropriate associated attribute
number. One of these is controlling and one is dependent. This concept
doesn't really exist in UV and UD, except in these types of attributes (UV
only).
So, if you're using a front-end tool you can define an "A" or "S" type
dictionary as multi-value by putting an "M" or "S" in attribute 11 of the
dictionary then tell your tool to look there.
Hope this helps.
Bill

Stuart,
If you make either one of these S, LIST DICT still
displays the depth and assoc as M not S
On what does it base this decision. It looks like
Universe assumes all A types are inherently multivalue.
