Specifies the name of the library you are compressing. The -compress parameter removes extra spaces that occur in the library as a result of repeated adds or deletes.

To compress a library, PROLIB creates a temporary file that requires an area of disk space equal to the size of the compressed library. Before compressing a library, make sure you have enough disk space for the temporary file. Temporary files have names that begin with the letters PLB, followed by numbers and possibly letters.

If your system goes down during a compress operation, the temporary file might remain on your disk. Delete this file to free up disk space. The original library will not be damaged.

Repeated adds create empty spaces in the library over time. To minimize the rate at which these empty spaces are created, you can use one command instead of many. For example, instead of entering the following commands:

Enter this command:

You can use the -list parameter to determine how much space in your library is unused.
