isCOBOL General

These errors mean that a java class was not found by the JVM. It can be returned at startup if the main program name has not been passed correctly in the command line (remember that Java is case-sensitive and the .class extension should be omitted)... Read More

Starting with Java 11, the Java runtime is DPI-aware by default.On displays configured above 96 DPI (for example 120, 150 or 200 DPI), Java automatically scales UI elements. For standard isCOBOL GUI applications this may result in: resized UI... Read More

a { text-decoration: none; color: #464feb; } tr th, tr td { border: 1px solid #e6e6e6; } tr th { background-color: #f5f5f5; } The START I/O statement supports the WHILE LIKE clause, which allows you to search for records that match... Read More

The iscobol.properties file has two main uses: as a license file and as a configuration file for the compiler or the runtime framework.  During installation, the setup asks if the user wants to activate the licenses or skip the activation. If the... Read More

a { text-decoration: none; color: #464feb; } tr th, tr td { border: 1px solid #e6e6e6; } tr th { background-color: #f5f5f5; } If your program uses a hard-coded value for the data file name, you can define an alternate name as an... Read More

a { text-decoration: none; color: #464feb; } tr th, tr td { border: 1px solid #e6e6e6; } tr th { background-color: #f5f5f5; } Sometimes, a COBOL application needs to store data in temporary files. These files are typically deleted... Read More

If you need to read data from a file written in a different encoding than the default you can use the attached java function to translate the data from the source encoding to the destination encoding.  The attached COBOL program reads a sequential... Read More

It’s very important to keep in mind that the isCOBOL configuration is built up by merging multiple files and settings. The runtime framework searches for configuration properties in the following list of places: The configuration file specified... Read More

You can create a simple or complex type definition that can be consistently and easily reused with other variables without having to copy and paste the contents of the original one. This is done using the TYPEDEF clause in the data description.  ... Read More

To solve this problem you can normally read the line-sequential file, then before using the contents of the record you can call a specific function for the translation. If you’re using isCOBOL 2023R1 or later, you can use the C$STRING_CONVERT... Read More
