The c-tree File Connector The c-tree File Connector allows to work on c-tree files managed by c-tree by separating ISAM native access from java process. The File Connector executable is provided along with isCOBOL: Platform Executable Linux/ Unix $ISCOBOL/bin/fscsc Windows %ISCOBOL%\bin\fscsc.exe In order to make isCOBOL use the c-tree File Connector as file handler, the following setting must appear in the configuration: iscobol.file.index=fscsc The fscsc file handler runs the executable file fscsc. If this file is not in the system Path, you can specify its full name by setting the iscobol.file.connector.program configuration property. The c-tree File Connector reads only the configuration provided by CTREE_CONF. See Configuring the client through CTREE_CONF for details.
