CIGAL Reference Manual, Chapter 4 (Variables): wflags
Wflags -- Internal variable controlling the use of split screen windows
usage: wflags = value
WFLAGS is a bit-flag controlling whether to switch output to video window 1 during execution of different commands. Each bit in WFLAGS represents a different CIGAL command, if that bit is 1 then window 1 will be used, otherwise window 0 will be used for that command.
The meaning of the bits in WFLAGS is:
10o NOERASE Don't erase when switching to Window 1 40o EDIT Switch to Window 1 for EDIT command 100o HELP Switch to Window 1 for HELP command 200o SHOW Switch to Window 1 for SHOW command 400o DIR Switch to Window 1 for DIR command 1000o JOU Switch to Window 1 for JOURNAL command 2000o LIST Switch to Window 1 for LIST command 4000o MENU Switch to Window 1 for MENU command 10000o TYPE Switch to Window 1 for TYPE command 20000o ECHO Switch to Window 1 for implicit TYPE command 40000o ERR Switch to Window 1 for error messages 100000o WATCH Only use Window 1 for displaying WATCH data
Overall control for switching windows depends on the VWINDOW variable (see VWINDOW(4)). Set VWINDOW to force all output to either window regardless of the settings in WFLAGS.
NOTE: The WATCH command is unusual in that once WATCH has been called to display data values in window 1, then all other commands will print their output in window 0 regardless of their WFLAGS settings, until the WATCH command is inactivated (see WATCH(2)). The WATCH bit in WFLAGS should normally not be changed except by the WATCH command itself.
