==== DSPACE ====

DSPACE computes the amount of space remaining for a 
specified disk.

<code>
DSPACE(disk, space, clusters, clust.size, sect.size, disk.size)
</code>

==== Using DSPACE ====

Use DSPACE to return the number of bytes (and other 
operating system data) remaining on a specified drive.

=== disk ===

Use disk to pass the drive where the disk is to be found.  A 
colon is not required (i.e., either C or C: is fine).

=== space ===

DSPACE will return in space the number of bytes available.

=== clusters ===

DSPACE returns in clusters the number of clusters available.

=== clust.size ===

DSPACE returns in clust.size the number of sectors per cluster.

=== sect.size ===

DSPACE returns in sect.size the number of bytes per sector.

=== disk.size ===

DSPACE returns in disk.size the number of clusters per disk.

==== Values returned ====

The remaining disk space, number of clusters, size of 
clusters, size of sector, and number of clusters per disk 
are returned in the respective argument list parameters.

==== Correct Use of DSPACE ====

<code>
/* The following code reports available space on drive C:, 
as well as other statistics. */

DECLARE SUBROUTINE DSPACE, MSG

disk = "C"

DSPACE(disk, space, clusters, clust.size, sect.size, disk.size)

text     = "Space available: ":space
text<<-1>> = "Number of clusters: ":clusters
text<<-1>> = "Cluster size is: ":clust.size
text<<-1>> = "Sector size is: ":sect.size
text<<-1>> = "Disk size is: ":disk.size

MSG(text, "", "", "")
