The de command invokes the system debugger
from the BASIC/FlashBASIC debugger. Issuing a g command from the system debugger returns control to the BASIC/FlashBASIC
debugger. The de command is identical to the debug
command at TCL.
Warning: The system debugger is extremely powerful
and should not be used without a strong working knowledge of
its capabilities and features. Using the system debugger incorrectly
could result in corrupt data or a system crash.
