.RESET_SESSION

The .RESET_SESSION command resets much of the state of an IDL session without requiring the user to exit and restart the IDL session.

Returns current execution point to $MAIN$ (RETALL).

Removes all breakpoints.

Clears the path cache (see PATH_CACHE for details).

Closes all files except the standard 3 units, the JOURNAL file (if any), and any files in use by graphics drivers.

Disables SHMDEBUG mode.

Destroys/Removes the following:

All local variables in $MAIN$.

All widgets. Exit handlers are not called.

All windows and pixmaps for the current window system graphics device are closed. No other graphics state is reset.

All common blocks.

All handles

All user defined system variables

All pointer and object reference heap variables.

Object destructors are not called.

All user defined structure definitions.

All user defined object definitions.

All compiled user functions and procedures, including the main program ($MAIN$), if any.

Any memory segments created by SHMMAP.

The current values of intrinsic system variables are retained.

The saved commands and output log are preserved.

Graphics drivers are not reset to their full uninitialized state. However, all windows and pixmaps for the current window system device are closed.

The following files are not closed:

Stdin (LUN 0)

Stdout (LUN -1)

Stderr (LUN -2)

The journal file (!JOURNAL) if one is open.

Any files in use by graphics drivers (e.g. PostScript).

Dynamically loaded graphics drivers (LINKIMAGE) are not removed, nor are any dynamic sharable libraries containing such drivers, even if the same library was also used for another purpose such as CALL_EXTERNAL, LINKIMAGE system routines, or DLMs. See the .FULL_RESET_SESSION executive command to unload dynamic libraries.

Message blocks are not removed. See the .FULL_RESET_SESSION executive command to remove message blocks loaded by DLMs or created using the DEFINE_MSGBLK or DEFINE_MSGBLK_FROM_FILE routines.
