.b 3 .center;ABSTRACT The video editor VTECO is an CRT-oriented text editor with capabilities similar to those available on advanced word processing systems. Combined with RUNOFF, VTECO provides a powerful word processing facility for RSX11M and VAX VMS users; combined with other language processors, VTECO provides a very effective program preparation tool. Throughout each editing session, VTECO automatically maintains on the CRT screen an exact image of the visible portion of the file. While no knowledge of TECO is required to run VTECO, all of the facilities of TECO are available and new editing functions can be added easily. VTECO is an extensively modified version of RSX11M TECO V34. It has been run under RSX11M (V3.0-V3.2), RSX11M-PLUS (V1.0), and VAX VMS with DEC VT100 and VT52, Lear Siegler ADM3A and ADM-42, InterTube Video Terminal III, and Datamedia Elite 1520A terminals. VTECO supports multi-user operation and includes video I/O optimizations. Additional terminal types can be added easily. This report includes extensive user documentation for VTECO and complete system documentation for both the TECO modifications and the TECO language source for VTECO.
