Dual Menu Approach to Symbolic Prompting

This is a method for providing display information in menu form to an operator of a cathode-ray tube (CRT) keyboard terminal where repetitive prompting is eliminated and the amount of information keyed in by the operator is kept to a minimum.

This method maximizes the use of a very small CRT screen (240 characters) when prompting the operator for a series of symbolic field entries from RPG input specifications, that are used as input to the program.

The dual-menu approach provides two menus on the CRT screen at one time. One menu contains the symbolic field names taken from the PPG input specifications. This first menu is variable in length and may not fit on the CRT screen in its entirety, but it can be rolled-up and rolled-down to locate the proper symbol. The second menu is stationary and contains any optional functions that the operator may desire such as, accumulate the field, or self-check the field.

The operator is able to select a field he desires, by simply keying in a letter that corresponds to that symbolic field name. He may optionally choose a function, by keying in a number that corresponds to that function after the letter just keyed.

Fig. 1 depicts an RPG input specification that serves as input to the program for purposes of building the first menu.

Figs. 2-6 depict the CRT screen as it would appear to the operator. The E in Figs. 2, 3, 5 and 6 represents the entry key.
