Block Overstrike in an Information Processing System

This article discloses a technique for overstriking or double underscoring a block of displayed text with a single character by surrounding the defined information with Begin/End Overstrike codes which are transparent to the information processing system operator.

An overstrike function is provided for overstriking a block of text with a single character. The overstrike function is invoked by depressing the overstrike (OVER) key. When the overstrike key is depressed, the system places the message, "Overstrike Text", in the context field on the first status line of the display and places the message on the prompt line, "Overstrike What?".

At this point the operator defines the block of text to be over-struck. If the operator only wants to overstrike one character, then the operator may depress the ENTER key without moving the cursor. The cursored character is initially video reversed.

If the operator wants to overstrike more than one character, then the operator must use the cursor keys to define the block. The operator may define the block in either a forward or backward direction. Once the block has been defined and the ENTER key is depressed, the system displays the following on the Prompt Line: "Overstrike with what character"? The operator then types the desired character to overstrike with and depresses the ENTER key. The character specified here may be any printable graphic character.

Once the Enter key is depressed, the system inserts a Begin Overstrike BOS) graphic, preceding the block of text, and an End Overstrike (EOS) graphic, immediately following the block of text. The cursor remains at the end of the overstrike block (i.e., where it w...
