Notes:
*
marked items are FlagShip extensions to Clipper.
**
marked items depends on the used Unix or Windows system.
Please see additional details in the FlagShip manual, section LNG and REL. The on-line manual named "fsman" is installed automatically also with the test drive. Printed manual (1500+ pages) is a part of the usual distribution (except for Linux, Windows), or can be ordered separately.
