Variable size and position dialog area display system
First Claim
1. Apparatus for providing a variable size and position alphanumeric area for a display screen normally supplied with alphanumeric information in the form of a plurality of consecutive lines positioned at consecutive locations, wherein said alphanumeric area normally consists of a lesser number of lines than said plurality of consecutive lines and constituting a subset of said plurality of consecutive lines, said apparatus comprising:
- first means for selectively providing numerical identification of the starting line and the stopping line of a group of lines comprising said subset to be displayed, said numerical indication being in the form of a line of data from an input data bus,and a counter adapted to receive the numerical identification of the starting line for counting during the normal occurrence of said plurality of lines as said alphanumeric information is received until said starting line is reached to produce a display enabling signal to enable display of said alphanumeric information and adapted for counting until the stopping line is reached for discontinuing said enabling signal for disabling display of said alphanumeric information.

Abstract
A variable size and position dialog area or alphanumeric area is provided for the screen of a computer terminal in response to a single line of data from a data bus, containing the numerical indication of the initial line of a plurality of lines of alphanumeric information to be displayed and the numerical indication of the last line of a plurality of lines of alphanumeric information to be displayed. The numerical indications are successively loaded to a state machine operating as a counter which disables the alphanumeric display during a first counting operation and enables the alphanumeric display for the duration of a second counting operation.

3. The method of displaying a group of lines from a plurality of lines of alphanumeric character information selected for display on a display means, wherein said plurality of lines of alphanumeric character information are normally provided as input to said display means, and the lines of said group for display are fewer in number than said plurality of lines, comprising the steps of:
-
receiving data for the display as lines of alphanumeric information, storing a first numerical indication of a first line of said group of lines to be displayed on said display means, storing a second numerical indication of a last line of said group of lines to be displayed on said display means, counting lines provided to said display means until said first numerical indication is reached and thereupon enabling said data for display as lines of alphanumeric information, and counting the number of lines displayed until said second numerical indication is reached and thereupon disabling said data for disabling display of said lines of alphanumeric information. - View Dependent Claims (4, 5)

6. Apparatus for providing a variable size and position alphanumeric area for a display screen normally supplied with alphanumeric information in the form of a plurality of consecutive lines positioned at consecutive locations, wherein said alphanumeric area normally consists of a lesser number of lines than said plurality of consecutive lines and constituting a subset of said plurality of consecutive lines, said apparatus comprising:
-
first means for selectively providing numerical identification of the starting line and the stopping line of a group of lines comprising said subset to be displayed, and a counter adapted to receive the numerical identification of the starting line for counting during the normal occurrence of said plurality of lines until said starting line is reached to produce a display enabling signal and adapted for counting until the stopping line is reached for discontinuing said enabling signal, wherein said counter comprises a state machine adapted to be shifted to consecutive states by a clock responsive to the occurrence of successive lines of alphanumeric information. - View Dependent Claims (7)

8. The method of displaying a group of lines selected for display on a display means from among a plurality of lines of alphanumeric character information provided to said display means, comprising the steps of:
-
receiving a plurality of lines of alphanumeric character information, receiving a data input for identifying said group of lines among said plurality of lines, and in response to said data input causing said display means to be enabled for the portrayal of alphanumeric character information only during times when lines are received that are identified by said data input. - View Dependent Claims (9, 10, 11)
