Appendix C LIMITS
Data names The number of items that can be displayed on an INFORM/V
(items) per Data Names Menu depends on the database that the user is
Data Names Menu reporting from:
IMAGE/V databases - 128 items can be
displayed.
TurboIMAGE/V databases - 256 items can
be displayed.
These limits apply both when Groups are made up from the
databases and when databases are accessed directly.
KSAM or MPE The number of data names that can be included in a KSAM
file or MPE file record is limited by the DICTIONARY/V
requirements that only 128 items can be defined for a
KSAM or MPE record.
Items in a The number of items that can be included in a report is
report 128.
User-defined The number of user-defined data names allowed depends on
data names the number of permanent data names in the Group.
User-defined data names can be added to a Group until
the limits given above for Groups are met.
When a report is being drawn from a KSAM or MPE file, INFORM/V includes
all items defined in the data dictionary for that file in its internal
table, even though all items are not being reported. If items are being
drawn from more than one file, it is therefore possible that limits will
be exceeded even though very few items are included in a report.
For example, assume that a KSAM file having 50 items defined in the data
dictionary has 5 items defined in a Group. A second KSAM file has 20
items defined in the data dictionary, but only 5 defined in the Group.
If a report calls for one item from each file, the internal table will
contain 70 items (50 plus 20).
When a child item is being reported, INFORM/V includes the parent item,
as well as the child item, in the internal table.
