Disk Space Analysis Program (DSAP)
The percentages provided in parentheses (for the summary of space use) are percentages
of the total disk pages on the volume. The percentage of allocated pages added to the
percentage of free pages is not exactly equal to 100 percent. The space representing that
difference is used by the system tables (containing the disk directory, free-space table,
spare-tracks table, volume label, and others).
