SHOWLOGO is an assembler program to display a graphics picture
until the user presses a key. It is most often used as the last command
in the AUTOEXEC.BAT file to display a company logo or other picture
whenever the system is booted. The picture displayed is imbedded in the
SHOWLOGO program so that it can be quickly transferred to the screen
buffer. Any graphics picture, saved in the BASICA BSAVE format, can be
substituted for the current logo by using DEBUG. (Eugene Ying's
excellent PC Picture Graphics program creates pictures in BSAVE format
which can be used in SHOWLOGO.)

The background and color palette for a medium resolution graphics
picture or the foreground color for a high resolution graphics picture
can be set. The ability to enable or disable Shift-PrtSc can also be set.

The following program illustrates the creation and saving of a
medium resolution graphics screen in BASIC and creation of a new logo

Assume that C is the default drive, which contains BASICA, DEBUG and
