DRAW BOX FROM

Description:
This command will draw a box from the specified upper left coordinates
to the specified lower right coordinates using a single line.
Optionally, the box can be filled with a specified dGE pattern from 0 to
20.  Unless a pattern is specified, the box will be clear.

Syntax:
DRAW BOX FROM <Pos1_a>,Pos1_b> TO <Pos2_a>,<Pos2_b> ;
   [PATTERN <pattern>]
   [BEVEL]

Arguments:
<Pos1_a> is the upper left row screen coordinate of the box.
<Pos1_b> is the upper left column screen coordinate of the box.
<Pos2_a> is the lower right row screen coordinate of the box.
<Pos2_b> is the lower right column screen coordinate of the box.
<pattern> is the dGE pattern number for the interior of the box.
[BEVEL] will cause the box to have three dimensional characteristics
  as though it was a raised button.
