double(3G)double(3G)NAMEdouble - sets the display mode to double buffer mode
FORTRAN 77 SPECIFICATION
subroutine doublePARAMETERS
none
DESCRIPTIONdouble sets the display mode to double buffer mode. It does not take
effect until gconfi is called. In double buffer mode, the bitplanes are
partitioned into two groups, the front bitplanes and the back bitplanes.
Double buffer mode displays only the front bitplanes. Drawing routines
normally update only the back bitplanes; frontb and backbu can override
the default.
In double buffer mode, gconfi calls frontb(.FALSE.) and backbu(.TRUE.).

This routine is available only in immediate mode.
