The NIST Part 21 Exchange File Toolkit is a C software library for building software tools for the exchange of instance information in a STEP environment. An example application is included which reports syntactic and semantic errors in Part 21 files. It is greatly improved over the previous public release both in speed and coverage of the specification. This is a simple use of the NIST Part 21 Exchange File Toolkit. Includes classes to support enumerated and logical types, Strings, Express aggregates, STEP exchange files, and sets of data instances.
