6. A computer-implemented method for extending editing capability of a system editor executing on a digital computer, the system editor having a core set of commands, the method comprising the steps of: creating, in a high level programming language, a library separate from the system editor and core set of commands, the library containing at least one new editing command and a namelist; and linking the system editor to the library to extend the editing capability of the system editor, wherein the step of linking further comprises the step of providing an interface in the system editor to access the new editing command with respect to a numerical position in the library, wherein the numerical position of the new editing command is determined by the namelist provided in the library, wherein the step of linking further comprises the step of providing a link file to allow access by the interface to a particular library; and the step of creating further includes the step of creating a plurality of different libraries of new and different editing commands, wherein each one of a plurality of users may have access to any combination of the plurality of different libraries by way of the link file.

The method of claim 6, further comprising the step of accessing the new editing command, wherein the step of accessing comprises the steps of: linking the system editor to the library; comparing the new editing command with the namelist; determining the numerical position in the library of the new editing command from the namelist; retrieving a set of compiled computer code at the numerical position for the new editing command; and executing the set of compiled computer code.
