OpenVMS Terminal Related Experience
Since founding the firm in 1978, Mr. Gezelter has worked extensively with
terminal handling and related communications. His activities included:
architecting, designing, implementing, and maintaining command procedures to configure
applications software and physical devices during the OpenVMS system
startup (and applications startup) processes.
architecting, designing, implementing, and maintaining forms management APIs
and related libraries using the extended functionality of the OpenVMS
Terminal Driver (IO$READVBLK|IO$M_EXTEND).
architecting, designing, implementing, and maintaining utilities to monitor the
operation of large numbers of terminals. In one notable case, such an
application (implemented using
Asynchronous System Traps, known as ASTs) was so efficient that it accumulated
infinitesimal CPU time over a period of several days (the system operators
-- on a MicroVAX II -- actually reported the program as broken --
insufficient CPU time used over a multiple day period)
implementing numerous DCL procedures to address a wide
range of client application and system management
speaking on terminal management and programming on OpenVMS
and related products at DECUS Symposia in the United
States, Canada, Switzerland, France, and Turkey.
