What causes an XVT error in IQ for Windows?

On Windows XP or later systems, the most common XVT errors are caused by incompatible printer drivers. Such XVT errors can occur even when a report is displayed only to the screen. Sometimes, the errors can be prevented by adding a printer in Windows using an older driver such as the HP LaserJet II and making that printer the default printer.

Because IQ for Windows has been discontinued, a better solution is to replace IQ for Windows with ODBCdL4 and an ODBC based report writer such as Crystal Reports. The ODBCdL4 server and driver provide ODBC access to UniBasic or dL4 data files. Current UniBasic or dL4 licenses include a license for ODBCdL4.

Why does my IQ for Unix license file get invalidated on a regular basis?

On most Unix systems, using the "-a" option with cpio alters the "change time" on a file in UNIX on output. Do not use the "-a" option when backing up files in the /etc/DCI directory or skip the /etc/DCI directory when performing backups.

This problem can be avoided by using a hardware passport device.

How do I compute a percentage subtotal in IQ?

The IQ User's Guide states "to create a subtotal that is a percentage in IQ for UNIX or Windows, you must multiply by 100 before dividing. For instance, to create a tuition percentage column rather than a tuition ratio column, perform the calculations in this order:

1. Multiply TUITION by 100 to get TEMP.

2. Divide TEMP by ORIG-TOTAL-DUE to get TUITION-PCT.

The proper order of the commands within your procedure would be:

MULTIPLY TUITION TIMES 100 GIVING TEMP.
DIVIDE TEMP BY ORIG-TOTAL-DUE GIVING TUITION-PCT."

How do I define a MRT record which contains multiple possible values?

If a MRT record does not contain unique record identification, then it is defined as a default record type. A default record type must be the very last record type defined. In addition, it should be defined as a recurring record. The Record ID Code Type, Location, Sub-field Offset, and Storage Size must be set to zero (0), one (1), zero (0), and zero (0) respectively. Furthermore, the Record ID Code must also be set to zero (0).

Please refer to "IQ Data Dictionary Reference" manual for a detailed description.

How can I detect if IQ is performing a fast key search?

IQ performs a fast key search only on primary files. This process can be identified when the number of records processed is equal to the number of records found.
Back to IQ FAQ's

How can I detect if IQ is performing a smart sort?

IQ performs a smart sort when the field being sorted is in the index of primary files. This process can be identified if the initial sort is completed in a single pass.

What is "ODBC error: Microsoft (ODBC SQL driver) (SQL server incorrect syntax near DBO)"?

IQ has detected a 32-bit ODBC driver, instead of Microsoft?s 16-bit ODBC driver.
Back to IQ FAQ's

How do I recover from "ODBC error: Microsoft (ODBC SQL driver) (SQL server incorrect syntax near DBO"?

IQ for Windows uses the 16-bit ODBC driver, instead of the 32-bit ODBC. Installing the 16-bit ODBC resolves this problem.
Back to IQ FAQ's

Why do I get the word "reserved" in the upper left corner of the screen on starting IQ 3.1?

IQ3 will not run with an IQ2 SSN and IQ3 reports ?reserved? mistakenly. A later version of IQ3 correctly reports a security violation.

Which printer configuration file does IQ for UNIX uses for background print?

IQ for UNIX uses iqprtcfg.dat as the configuration file for background print.
Back to IQ FAQ's

Why do I get "ODBC ERROR MESSAGE: ODBC is not installed on this machine."?

When IQ for Windows is started with an empty data dictionary, like the distributed ddmaster.dat, it attempts to use the 16-bit ODBC driver. The above message is then reported if the ODBC driver is not installed. Please install the Microsoft 16-bit ODBC driver to avoid the above warning.

How can I have IQ skip deleted records in a FoxPro file?

The "Show Deleted Rows" option may be turned off from the ODBC FoxPro Setup screen.

What does the message, "Code 1:x, Code 2:y" mean?

These types of errors are fatal and "are caused by many reasons, including the inability to locate or open an IQ system file, improper or incorrect security permissions, data dictionary setup, and hardware constraints or failure" (Intelligent Query and IQ Access User's Guide, p. A-6). Error "Code 1:" and "Code 2:" are listed in columns one and two, respectively.

IQ fatal errors are listed in "Intelligent Query and IQ Access User's Guide", appendix A.

How do I recover from Code 1:25, Code 2:-4?

According to "Intelligent Query and IQ Access User's Guide", this error occurs when IQ could not open a supporting file, such as iqcap, iqconfig.dat, iqprtcfg.dat or the data dictionary file.

Please refer to "Intelligent Query and IQ Access User's Guide", appendix A for a detailed description.

Can I use an IQ2 iqcap terminal file with IQ4?

Yes, IQ2 iqcap files are fully compatible with IQ4.
Back to IQ FAQ's

How do I prevent my IQ process from running after disconnecting from my telnet or dialup session?

On a Unix system, orphaned processes may be avoided by adding a XS record and then setting its value to one in the iqconfig.dat file. These orphaned IQ processes may result in a slow system.

Is IQ year 2000 compliant?

IQ for Unix version 4 is certified to be Year 2000 compliant. IQ itself is a query and report generator and hence, was not designed to interpret users? data. However, since many users have 2 or 3 digit years stored in their data files, DCI enhanced IQ to handle year 2000 problems. Specifically, IQ for Unix version 4 has been enhanced to:

• Correct Year 2000 ascending and descending sort of 2 digit year date fields for UniBasic and dL4 files, including dL4 FoxPro Full-ISAM files. The sort will work correctly, even if a 2 digit year is stored as part of key data. For example, "010100" will appear before "010199" in a descending sort. Likewise, "010100" will appear after "010199" in an ascending sort.

• Correct time calculation of 2, 3, and 4 digit year data fields for UniBasic and dL4 files, including dL4 FoxPro Full-ISAM files.

• Correct leap year calculation for 2, 3 and 4 digit years for UniBasic and dL4 files, including dL4 FoxPro Full-ISAM files.

• IQ interprets dates as specified in the data dictionary date layout as follows:

a) 4 digit years (Y4) are taken "as is".
b) 3 digit years (Y3) are added to the DEFAULT century as configured in IQCONFIG.DAT item CD.
c) For UniBasic and dL4 files, 2 digit years (Y2) are converted to be in the nearest century based on a plus/minus 50 years rule. A two digit year is thus assumed to be within 50 years, plus or minus, of the current year as returned by the system. For example, if the system returns 1998 as the current year, then the year 47 will be interpreted as year 2047, and year 49 will be interpreted as year 1949.
• A new IQCONFIG.DAT item CD allows the user to override the default century (1900) for a three digit year.year.

A new IQCONFIG.DAT item CD allows the user to override the default century (1900) for a three digit year.

Is IQ supported in a network environment?

Although IQ is not specifically tested in a network environment, it should work in a properly configured NFS system which can properly handle record locking. The product itself does not use any system calls specific to networking.

IQ for Windows should work properly in a Microsoft network file system. It is, however, not tested for Novell networks.
Back to IQ FAQ's

Can I use Samba with IQ?

Yes, but if files on the Unix/Linux server are to be accessed concurrently by both Windows and Unix applications, it may be necessary to set Samba configuration options so that Window and Unix/Linux record locking are handled identically. Please check your Samba documentation for any references to record or file locking configuration.
