**CIGAL Reference Manual, Chapter 4 (Variables): sflags**
===== Sflags -- Integer variable controlling SKETCH options =====
**usage:  sflags = value**

SFLAGS, an internally defined integer variable, controls options related to how
the SKETCH command operates. The value of the SFLAGS parameter can be changed at
any time and remains set until it is explicitly modified again.  The meaning of
the SFLAGS settings are summarized below.  Combine levels by adding values.

     Value (octal)  Meaning:
       1      1o    Don't connect points if cursor has jumped; use MOVE
       2      2o    Paint region when cursor gets near starting point
       4      4o    Close loop when drawing gets near starting point
       8     10o    Measure length (& area) at end of each vector list
      32     40o    Don't sound bell while drawing
      64    100o    Use "rubberband" cursor for drawing
     128    200o    Allow cursor positions within menu region. The BACKSPACE
                     key can be used to toggle MENUs on and off.
     256     400o   Connect points in pairs only
     512    1000o   Only one entry per button press
