A pilot study was performed to experimentally assess the implications of CRT screen size and definition on text editing performance. The study manipulated line length 16, 32, and 64 characters displayed per line, window height 1, 4, 8, and 19 line text pages and edit field location text to be edited was located at the beginning, middle, or end of text messages to measure effects on text editing performance as measured by edit field location time, editing time, and errors. Of these, text location time and location errors as measured by vertical scroll reversals were significantly influenced by line length and edit field location.
