QUERY/iX Enhancements Respond to User Requests

LANGUAGE = NATIVE-3000
VERBOSE MESSAGES DISABLED.
TurboIMAGE Expanded Limits
The support of the TurboIMAGE Limit Expansion allows for the increased number of
datasets from 199 to 240, the increased number of data items from 1023 to 1200, and the
increase in paths into a master dataset from 16 to 64. QUERY/iX will utilize the new
limits on systems with the TurboIMAGE version HP30391C.09.00 and later. If the new
DBUTIL option flag of OLDINFOLIMITS is enabled for a database, QUERY/iX will
function normally as it uses the new DBCONTROL Mode 20 to inform TurboIMAGE that
QUERY code supports the new expanded limits.
FIND by Record Number
The long requested Find-by-Record-Number enhancement has been implemented. This
new format of the FIND command permits the retrieval of a specific record in a dataset.
The form of the new feature is:
FIND [DATA BASE NAME:] DATA SET NAME.#RECORD NUMBER
The record number is preceded by a "#" and is the record offset into the dataset that is to
be retrieved. The record number may be a decimal number (the default) or an octal value
indicated by a "%" after the "#", or a hexadecimal value indicated by a "$".
For example, to read the fifteenth record in the dataset INVOICES, one could use any of
the following commands:
FIND INVOICES.#15
FIND INVOICES.#%17
FIND INVOICES.#$f
After a record is retrieved, all of the usual QUERY commands may be used on the record.
If the record number requested does not exist, QUERY will return a "NO ENTRY" or
"DIRECTED END OF FILE" followed by "0 ENTRIES QUALIFIED."
Floating Decimal Option with Native Mode QUERY
The PARM=%777 option is now available with the Native Mode version of QUERY. It was
previously only available with the Compatibility Mode version of QUERY.
The availability of this feature on Native Mode QUERY will allow the Compatibility Mode
version of QUERY to be discontinued in a future release. With this change, Native Mode
Query (QUERY.PUB.SYS and QUERYNM.PUB.SYS) now provides a superset of the
Compatibility Mode QUERY. All use of QUERYCM should now be transferable to
QUERY.PUB.SYS. Thus, QUERYCM.PUB.SYS may no longer be updated and will be
replaced on a future release with a SYMLINK to QUERY.PUB.SYS.
