My name is Tom Brennan, and I was an IBM mainframe systems programmer from 1983 to 2013, then joined an IBM Business Partner to support mainframe software and hardware for various clients. Although the mainframe is my primary workload, I still like to find time to work with Windows and Linux programming.
Prior to Windows, my spare time was often filled with programming various mainframe utilities, mainly to aid in the process of installing and maintaining software in a large mainframe environment. Assembler was my primary tool, and I believe those utilities allowed me to do my work faster, making up somewhat for the inevitable loss of good people to non-mainframe computing support.
Vista TN3270 was also designed to speed up my regular mainframe work. With it I tried to correct some of the deficiencies I saw with the various commercial and shareware emulators I've used over the years. Being an emulator user and emulator programmer puts me in a unique position to develop a product that works best for someone who does my particular type of work.
I hope Vista TN3270 can help you in your mainframe work, as it has helped me.
