FUNCTION:
_PopBox( nTmax, nLMax, nBMax, nRMax, nType, cFill ) --> NIL
PARAMETERS:
nTMax : Top Row
nLMax : Left Column
nBMax : Bottom Row
nRMax : Right Column
nType : Type of Box Characters to use
cFill : Character to use to fill box (Default SPACE)
SHORT:
"Exploding" screen boxes.
DESCRIPTION:
_PopBox() "explodes" a box onto the screen stopping at the given coordinates.
Optionally, you may specify the box characters. Default box is Double
Top/Single Side.
NOTE:
Due to the different CPU speeds of various computers, the box may "explode"
so fast as to be unnoticeable. This can be controlled by use of a
DOS environment variable
SET BOXDELAY=6000
This value is detected if present and used as a delay factor between each
step of the "explosion" to slow the process down on fast computers.
EXAMPLE:
_PopBox(10,10,15,70)
Result: All default values except for coordinates.
