3. Creating and Assigning Variables Variables are created and assigned using the Let command For example Let x 3 assigns the value 3 to the variable x Note that Let is not optional as it is in most forms of BASIC You can also assign complex numbers and strings e g Let x 5 1 Let s This is a string All of the above are scalar that is they contain only one value Variables may also be single dimension arrays called vectors Vectors are described in the next section New line Character Vectors To enter a new line character use W If you need a literal double backslash enclose it in quotation marks i e W Note however that the use of W doesn t work inside braced substitutions To use a line feed in a braced substitution assign the whole string to a variable then put the variable inside the braces E g Let error Error Too many nodes MessageBox error Vectors can be created using a bracketed list with a function that returns a vector or by the simulator which creates a number of vectors to represent node voltages and device currents A bracketed list is of the form expressionl expression2 E g let v 1 3 9 Functions and simulator vectors are described in following sections Vectors like other variables may also contain strings or complex numbers but all the elements must be the same type The Script Language 23 Individual elements of vectors may be accessed using square brackets

User Defined Key and Menu Definitions Virtually the entire user interface is accessed through menus or keys all of which may be redefined deleted or replaced The only parts of the UI which are not accessible are the tool bar buttons and the mouse keys These have fixed definitions and may not be modified by the user In principle it is possible to define completely new menus which bear no similarity with the built in menus A more normal use of menu and key redefinition would probably be to add a special function or perhaps to delete some unused menus Menus are defined using the DefMenu command and keys can be defined with the DefKey command Unless you only wish to make a temporary definition it is best to place DefMenu and DefKey commands in the start up script so that they are automatically defined for all future sessions Key definitions may be context sensitive That is the definition is dependent on which type of window is currently active See DefKey command for more details To find out the standard definition for menus and keys use the commands ListStdMenu and ListStdKeys respectively These list such definitions to a file A large number of these simply call a script that performs the menu function Others carry out the relevant operation directly Rearranging or Renaming the Standard Menus Menu Shortcuts The standard menu definitions are loaded from the built in script menu when the program first starts The source fo

Each type of graph object possesses a number of properties which determine characteristics of the object Some properties are read only and are either never altered or can only be altered indirectly Other properties can be changed directly using the command SetGraphAnnoProperty The labels for curves axes and the various annotation objects are examples of properties that may be edited Graph Object Identifiers the ID Each instance of a graph object is uniquely identified by an integer value known as its ID Valid IDs always have a value of or greater IDs are returned by a number of functions see below and also a number of the objects possess properties whose value is the ID of a related object Once the ID of an object has been obtained its property names can be read and it property values may be read and or modified The following functions return graph object IDs Note that all functions return object IDs belonging to the currently selected graph only except for GetGraphObjects which can optionally return IDs for objects on a specified graph GetAllCurves Returns the IDs for all curves GetALLY Axes Returns the IDs for all Y axes GetAxisCurves Returns IDs for all curves attached to specified y axis GetCurrentGraph Returns the ID for the currently selected graph sheet GetCursorCurve Returns information about curve attached to the main cursor including its ID GetCurveAxus Returns ID of y axis associated with a curve
