Use PROLIB Memory (-plm) to allocate a 512byte cache for a standard library directory.

Otherwise, when using a standard library, the library's internal directory is loaded into memory. The directory is used to access the r-code files stored in the library. This parameter slows the library's speed of access but increases available memory. If you specify -plm with memory-mapped libraries, the AVM ignores it. For more information on r-code libraries, see Manage ABL Applications and Develop ABL Applications.
