Abstract

This invention provides the word processing function of the Tab key for users with data processing backgrounds. The Tab key on the IBM Displaywriter and the Field Advance key on the IBM 5251 display station occupy the same relative position on the two keyboards, but the function performed by these keys is significantly different. Pressing the Tab key on the Displaywriter causes a tab character to be inserted into the text (which creates a tab field) and the cursor is moved to the first position of this tab field. If data exists on the line, inserting a tab character in this manner can cause rather dramatic shifting of data to the right. Once a tab field has been entered, the way that data is displayed on the screen is determined by the corresponding tab stop.

T:abkey Function for Data Processing Users on Unintelligent Display Stations

This invention provides the word processing function of the Tab key for users with data processing backgrounds. The Tab key on the IBM Displaywriter and the Field Advance key on the IBM 5251 display station occupy the same relative position on the two keyboards, but the function performed by these keys is significantly different. Pressing the Tab key on the Displaywriter causes a tab character to be inserted into the text (which creates a tab field) and the cursor is moved to the first position of this tab field. If data exists on the line, inserting a tab character in this manner can cause rather dramatic shifting of data to the right. Once a tab field has been entered, the way that data is displayed on the screen is determined by the corresponding tab stop. For example, keying data into a right tab field causes the cursor to remain motionless while the keyed data is shifted to the left. Keying data into a center tab field causes alternating cursor movement to the right and shifting of data to the left such that the data is always centered under the tab stop. Keying data in a decimal align tab field causes shifting of data to the left or movement of the cursor to the right depending on where the cursor is located in relation to the decimal point. Pressing the Field Advance key on the 5251 display station causes the cursor to move to the first position of the next input field on the screen. No character is inserted and no data is moved. Although these two keys have significantly different functions and are designed for two different environments...
