IQRDEV This is a queued messaging system something like DECMessageQ available in source for VMS here. Please note that the entire development environment was cloned and stored under the sub-directory IQR28A. This was done since the folks at Compaq decided to change many of the threads routines and their associated constants without regard for any backward compatibility. Be advised that some of the source code under the IQR28A tree will not compile under OpenVMS 7.3 and greater. The first release of the IQR code which is compatible with OpenVMS 7.3 is IQR V2.9. If you have questions please see Kevin DeYoung
