Local copies of Tcl source files
During a debugging session, the Tcl source files that are opened in NetBeans are local copies that are retrieved from the Debugger engine. They reside in a subfolder in the system's temp folder. In Windows, this is %TEMP%. In UNIX, this is /tmp.
The file name has the format CLUDtimestamp. For example, CLUD20170608002457504.
These local copies are read-only, and cannot be modified in NetBeans. You must use the Cloverleaf IDE to do Tcl source file editing. This ensures that changes that are made to tclIndex and to files on the server are also updated.
Then, you must debug hcitpstest to see the changes in NetBeans.
When the debugging session ends, the subfolder and all files in it are automatically deleted.
