The cut command removes the selected data from its original position, and the copy command creates a duplicate; in both cases the selected data is kept in temporary storage called the clipboard. Clipboard data is later inserted wherever a paste command is issued. The data remains available to any application supporting the feature, thus ...
The duplicate code base doubles the time required to implement changes which may be desired across both products; this increases time-to-market for such changes, and may, in fact, wipe out any time gains achieved by branching the code in the first place. Similar to above, the alternative to a copy-and-paste approach would be a modularized approach:
The Multics shell includes a run command to run a command in an isolated environment. [1] The DEC TOPS-10 [2] and TOPS-20 [3] Command Processor included a RUN command for running executable programs. In the BASIC programming language, RUN is used to start program execution from direct mode, or to start an overlay program from a loader program.
