New Limits  TurboIMAGE/iX : C.09.02
IMAGE and IMAGE/SQL have been enhanced so that the new limits for the 
above
elements are as follows:.
1. Number of items - 1200

2. Number of sets-240
Naming the datasets: Each database can contain up to 240 datasets. Each 
dataset is referenced by a unique dataset name. If the root file name is XXXX, 
the first dataset defined in schema will be XXXX01, the second dataset will be 
XXXX02, etc. up to XXXXO0. As earlier, any of these datasets can be a Jumbo 
dataset and any of these datasets can be expanded by using the capacity 
expansion in the schema, (if it is not Jumbo).

3. Number of paths for master - 64
The number of paths per master has been extended from 16 to 64. Note that 
this is only for master data sets
.
Creating the database and using it continues to be the same. The new 
definitions of items,sets, paths has to be in the schema after which a 
database is created using DBUTIL. Thenumber of paths from master to detail 
alone can be up to 64 but from detail to master  remains at 16 only.    

Compatibility
Any new databases created will have the benefit of these increased limits. 
However the new limits will not be applicable for databases created prior to 
this version of TurboIMAGE/iX. Databases created prior to this will continue to 
function the same, as there is full forward compatibility.
