To learn more about the IUA Class Library, start with the tutorial. The table of contents may be used to go directly to a section of the tutorial while the index may be used to find occurrences of keywords. You may find out more about the author from the Credits. A postscript file of the older, printed tutorial may be obtained from here.
Three implementations of the IUA Class Library were developed. One implementation is written using standard C++ classes and runs on sequential UNIX workstations. This version allows people to test their applications without having access to an IUA. A second version generates a CAAPP instruction stream. The third version also generates a CAAPP instruction stream but uses a modified Gnu C++ compiler (104,607 bytes) to specially handle the new classes and generate optimized code.
