Abstract

The advent of computer automation allows a user to perform on-line operations or initiate execution of a program by entering a command at a command line prompt. Often the commands are complex and their associated parameters lengthy. Reentering these commands, for any reason, is inconvenient to users. In addition, very often users only remember partial parameters or are not aware of the entire required parameters. This makes it difficult for users to reenter the entire command and its parameters. The user lacks a practical mechanism for storing and later retrieving commands to reuse the "previously keyed but not entered" command and its associated parameters. Some operating systems, such as OS/2*, have provided a mechanism for allowing previously requested commands to be recalled at the command prompt, e.g.

Mechanism for Virtual Command Line Buffer

      The advent of computer automation allows a user to perform
on-line operations or initiate execution of a program by entering a
command at a command line prompt.  Often the commands are complex and
their associated parameters lengthy.  Reentering these commands, for
any reason, is inconvenient to users.  In addition, very often users
only remember partial parameters or are not aware of the entire
required parameters.  This makes it difficult for users to reenter
the entire command and its parameters.  The user lacks a practical
mechanism for storing and later retrieving commands to reuse the
"previously keyed but not entered" command and its associated
parameters.  Some operating systems, such as OS/2*, have provided a
mechanism for allowing previously requested commands to be recalled
at the command prompt, e.g., shift up-arrow key.  Other programs,
such as Typescript, provide similar features.  However it requires
the user to execute the command before the command is stored.

      This article describes a mechanism to store and retrieve
commands.  However, this is different from the prior art that
requires the user to execute the command before the command is
stored.  The mechanism discussed here does not require the command to
be executed to be stored.  This mechanism provides a list of
commands, executed and not executed (i.e., typed on the keyboard, but
stored prior to its final entry and the user did not execute the
command), and their associated parameters that user previously had
entered on the command line for reuse.

      This mechanism includes a "Buffer Service" and a "queue-like"
buffer that can hold the command strin...
