Snow was written in order to do away with having to specify a
'set clipper=s1' in the environment. For all the time it took
to write, I hereby release it into the Public Domain.

|SNOW()
| ============================================================
|
Syntax:| SNOW()
|
Purpose:| To get or change clippers' internal flag that determines
| whether screen writes will be performed with snow on a
| color monitor.
|
Argument:| toggles the snow on or off. True (.T.) allows snow
| while false (.F.) disables it. The default setting is
| true (.T.) unless over-ridden by issuing a
| 'SET CLIPPER=S1' command before starting your program.
|
Returns:| A logical value.
|
| SNOW() returns the current snow setting.
|
Example:| The following example allows snow (possibly while drawing
| a lot of boxes on the screen.) which is allows faster
| screen updates:
|
| old_snow=snow(.T.)
| .
| .
| .
| (draw the boxes)
| snow(old_snow)
|
| Or at the begining of a program, snow(.F.) will disable
| snow for at least the summer.
|
|
Linking:| When linking your program, just include snow.obj in the
| link command line. If you have access to LIB from
| Microsoft, you can place snow in the EXTEND.LIB with the
| following command:
|
| LIB extend +snow;
