6 SCM Interface

DBSCM is a disk based, sorted associative array package (WB) integrated into the Scheme implementation SCM. These associative arrays consist of keys which are strings of length less than 256 bytes and values which are strings of length less than 64770.B. Associative arrays can be used to form a MUMPS style database which can be used to implement standard record structures without auxiliary files (see example in example.scm).

The WB implementation (compiled) adds about 66 kilobytes to the size of SCM.
