Analyzing Disk Space Usage With the Disk Space
Analysis Program (DSAP)
A report such as this is returned to your home terminal: 
Analyzing Disk Space Usage With the Disk Space Analysis Program 
(DSAP)
The Disk Space Analysis Program (DSAP) analyzes and displays how disk space is 
being used on a specified disk. It copies the disk directory and the disk free-space table 
to its own working storage and then, depending on which options you specify, 
manipulates this data to produce reports relevant to the use of disk space on that disk.
DSAP only measures the use of disk space; it makes no modifications to your system. 
DSAP is a privileged program and might not be available to all users on your system. If 
you have questions about your access to DSAP, check with your system manager.
DSAP is a noninteractive program that runs online while your disk is up. You run DSAP 
by entering a DSAP command with parameters at a TACL prompt. DSAP then takes 
control of your terminal and generates the requested report. If you enter DSAP at a 
TACL prompt without any parameters, DSAP displays help information, including run 
options, report options, and examples.
To use DSAP to quickly check the free space on a disk, enter:
> DSAP $disk, SHORT
