Return Value
Returns the value of the double-precision type number.
The content of the value is the shortest distance between the points and straight line.
Description
Specify the points to get the distance in <X Coordinate> and <Y Coordinate>.
The parameters a, b and c that make up the straight line ax+by+c=0 are stored in <Straight Line
Component>."a" to "c" are each stored in array elements 0 to 2.
This is mainly used to get the variance and deviation of the basic points with regard to lines gotten by the
Lsqumeth command.
Reference:
Lsqumeth command (p.238)
Example
Get the variance and deviation with respect to the straight lines gotten from the 4 points.(Please refer to
the Lsqumeth command for the method of determining a straight line).
Dim POSX#(3),POSY#(3),PARM#(2),DIST#(3)
'Initialize the line
For I&=0 To 3
GetUnitData I&+1,"X",POSX#(I&)
GetUnitData I&+1,"Y",POSY#(I&)
Next

For I&=0 To 3
'Calculate the shortest distance between the straight line and point.

Get the available space of the drive.
Dskf(<Drive Name>)
Parameters
<Drive Name> The drive name (character string) to get the available space.
Return Value
Returns the value of the integer.
The content of the value is the byte expression of the amount of free space available on the drive.
