- commands provided so as to arrive at a topology that matches
- the schematic.
- Defining the elements themselves is a simple enough task.
- Interconnecting them to realize the network at hand requires a
- small degree of thought. The easiest type of network is that
- in which all that needs to be done is cascade the elements,
- using either the CAS or CAX command. More elaborate networks
- will entail the usage of PAR and SER, the latter in the case
- of including emitter or source biasing components, as a typical
- example.
- Although no provision is provided for common-base to com-
- mon-collector transformations, this can be accomplished using
- IMA, CEB and IMA on the element in that order. This is handy
- in designing emitter/source followers and oscillators.
- When using any of the interconnections or transformations,
- the elements to be manipulated must appear in the network list-
- ing prior to the command. If not, an error will result when
- attempting to exit and no analysis will be possible.
- Lastly, one must always include an END satement. The
- entry for the element number is the same as for the number
- given to the completed network at the last interconnection.
- The network cannot be analyzed without it. Failure to include
- one will result in an error when exiting.

- H. EXITING THE EDITOR
-
- When selecting RETURN with a network in memory, a number
- of actions take place. These are:
-
- A. All elements are checked for uniqueness. The
- element number is checked against all other element numbers
- to ensure that the designation is unique.
-
- B. All interconnections and transformations are
- verified. The elements which are to be operated on are
- checked that they do in fact exist in the network. A com-
- mon error here is to issue a CAX (multiple cascade) and
- not have all of the elements in the network.
-
- C. All of the file elements are checked to see if
- they are on the disk. If not, the program cannot retrieve
- them to create a data fit.
-
- D. All data files are retrieved and a data fit is
- performed.
-
- If any errors are encountered in this process, the editor
- will jump to the display mode and will list the network, dis-
- playing the line in which the error was found in reverse field.
- It is then the users task to correct the error. It is not pos-
- sible to exit the editor with a faulty network in memory. If
- the user wishes to do so, the network must first be deleted.
