is-gui: variable

Default value: varies

The is-gui variable indicates whether a graphical version of Epsilon is running. In pure-text versions of Epsilon, this variable is zero. When the 32-bit Windows version of Epsilon runs under Windows NT/2000/XP/Vista, it sets this variable to 2. Under Windows 95/98/ME, it sets this variable to 3. The variable is 1 when the 32-bit version runs under Windows 3.1 using the Win32S package (though this is not supported). The 16-bit version of Epsilon for Windows 3.1 always sets this variable to 4.
