Phoenix can be executed via the windows start menu Start -> Querix -> Phoenix or via the command line (shell)

Users wanting to connect to a Linux database server using a Windows machine as the ‘front end', should note that the Linux server will need to be running some form of socket protocol (such as onsoctcp or ontlitcp) in order to establish the connection. You may also benefit from having the Informix SDK/Informix Connect installed on your local machine, so that you have a copy of setnet32.

When a project is created or imported, all the files present or added to it are included in the default build configuration. If you activate a non-default build configuration, you can exclude source files from the build, so that the project will be built without them.

One project can have more than one build configuration. A build configuration contains the information about the files which are included into the build.

To be able to work with a Hydra project, you need to import it into Lycia workspace. You cannot just copy project files into the workspace - this will not let Lycia work with them.

Below are the evaluation license restrictions on an unlicensed Hydra or Lycia package.

If the manual license activation fails, your license is either invalid (tampered) or the license was already activated previously.

To receive a license file, contact Querix or your authorized Querix reseller. To find out the contact details of your nearest Querix Partner, please contact Querix info@querix.com , or check our Querix partner location page.

How to add additional licenses

To import different resources one should select the appropriate import options depending on the resource.

In order to use some other repositories except CVS (for which Lycia offers a built-in client), you can install some additional plug-ins to your Lycia IDE.

If a 4GL library is not created within a project, but you still need to use it, you may import a library into a project and then link it to a program. Or you can link it as an external library.

Screen records are not reflected in the form area in any way. They can be viewed and edited only using the Properties view.

The database to which the form file will refer and to which the fields of the form may be linked is specified in the Properties View.

Lycia IDE supports two types of form files: the text form files (.per format) and the graphical form files (.4fm format). As many of the developers may need to import text form files into the Lycia IDE, the conversion of form files is enabled to convert these text forms into the graphical format.

Applications launched in graphical mode (using Phoenix or Chimera) are run on a GUI server. By default there are two GUI servers: GUI server on port 1789 which does not require authentication. GUI server on port 1791 with full authentication.

You can export individual files or a complete project to the file system using the Export wizard.

You can start the License Mangager from On Windows Go to 'Start->Querix->Tools->License Manager' menu. Command Line / Shell Change to the 'bin' directory located in the Querix directory and enter 'NTLicense.exe' for Windows and 'licensegen' for Unix/Linu

Demonstration applications are not shipped with Lycia. However, they are accessible form Querix CVS repository.

Go to 'Start->All Programs->Querix->Lycia->Lycia IDE' or use the shortcut created on your desktop.

Windows From the Startmenu -> programs, choose 'Querix' followed by 'HydraStudio'. Unix/Linux In the shell enter 'hstudio', this is located in $QUERIXDIR/bin.

Function keys should return values in the range 3000 to 3063 (F1 - F64). Technically, Shift-F1 is usually interpreted as F13, which would give a result of 301

Interactive debuggers don't tend to be a lot of help when dealing with SQL problems, especially since the SQL is dynamically translated.

Printing from a file on client side (Windows) You can print from a file by using the following code:

To deploy your application in a customer environment, you will need to install the Querix 'Hydra4GL' runtime package. This package is an integral part of the 'Hydra4GL' Compiler package, and consists of...

Error number -329 can occur for a number of reasons. This may be an error returned from the database engine, but it may also be because Hydra is failing to load the interface for the database you are trying to use. One of the common reasons for this, is that the necessary pre-requisites for working with the database are not present.

4make relies on program definition files for compilation. These files have a .def file extension, and contain information about the structure of the program.

When dropping tables in Oracle 10g you find that they are not actually being dropped. This is a new feature where when a table is dropped it is put into a kind of recycle bin and appears like the example below.

This issue is probably due to locale configuration. Check the output of the command 'locale'. This will list your current locale settings.

This problem is due to 'HydraStudio' not being able to find the C compiler.

In order to get the expected date format you will need to set the variable DBDATE in your environment, the value of this variable depends on the expected format of the date.

This example uses the F10 as an example of the 'F' key that is not working.

When I try to display some non-Latin letters (like German umlauts or line drawing characters) all umlauts are rendered as two characters, like "~N" or "~D".

There is no 'default DSN'. The application will assume that the name given in the 4GL database statement is an ODBC connect string. For example:

It is possible to select the connection to the database within the code using a dynamically created connect string... take the following code as an example for Oracle:

While compiling my application this error occured: Example Error opening DB driver: /usr/hydra.hp/lib/moddbdefault.sl can't open the module Querix Application Error No Database driver loaded or no Database specified.

The Querix 4GL provides a number of compatibility modes to bridge some of the differences in behaviour between Querix and Informix. There are, however, still some minor differences in the behaviour between the two products.

When you import your old programs into 'HydraStudio', you will also need to reference the associated files for your project. These files can include additional 4GL or form source files, unload (UNL) files, text files or config files for your program.

This error occurs when 8 bit data is being handled in a UTF8 locale. The UTF8 locale can not deal with the 8bit data and errors. The way to fix this is to change your locale to a 8-bit locale and recompile the program.

Where does the RUN statement search for the executable file to run? Does the Run statement search the Windows PATH variable or will it only look into the current directory?

You can use q4gl to import your i4gl files into 'Hydra4GL'. q4gl is in effect a drop in replacement for r4gl. Chapter 5 of the 'Hydra4GL' Developers guide describes the use of q4gl in detail.

The Informix MATCHES operator is a non-ANSI extension to SQL that has little equivalent support in other RDBMs systems

4make's behaviour may seem a little strange with .pic files. In order for .pic files to compile, you will need to append 'targ' to the name of the target you are compiling.

If during the compilation on UNIX/Linux either using 4make tool or using the IDE you get this error: libwsclient.so: file not recognized: File format not recognized collect2: ld returned 1 exit status

In 4GL the format of DATE and MONEY values depends on the default locale. If U.S. English is the default locale the following formats are applied...

Phoenix looks for your compiled programs in a default directory, which is defined by a file named 'querix' in '/etc/xinetd.d'.

During the installation of Phoenix you may get the warning message either at the end of the installation in the installation details or as a pop-up message during the installation. This message will inform you that you do not have mscal.ocx and/or comglg32.ocx components installed and Phoenix functionality is not fully available.
