Page 12: Welcome
Introduction MAN 0179 1.1 Welcome Welcome to the Malvern Basic Reference manual. This manual has been designed to give a detailed description of the operation and use of Malvern Basic. It gives details on the structure of a Malvern Basic program and details all commands available. Warning: You must remember that the Zetasizer or the samples to be measured are potentially dangerous if misused. - Page 13 MAN0179 Double-click - Press and release the mouse button twice in quick succession. If this is not qualified with a button description then assume it is the left button. Use the Mouse icon in Program Managers Control Panel to change the double-click speed. Dialogue Box - A window containing controls.

Page 14: Menu Commands
Introduction MAN 0179 Drag - An action with the mouse which involves moving the mouse while holding down the left mouse button. This is used for moving icons or making multiple selections in a list box. 1.5 Menu Commands Menu commands from the Malvern software are referred to in the form main menu-menu item. As an example, the command File-Save Sample refers to selecting the Save Sample item in the File menu. - Page 15 CHAPTER 2 Introduction to Zetasizer basic Artisan Scientific - Quality Instrumentation ...

Page 17: Introduction
Introduction to Zetasizer basic MAN 0179 2.1 Introduction The program language used in the Zetasizer software is similar to many other variants of Basic. Some features of other versions are not needed for our application and many extra functions have been added for specific use in particle sizing. Throughout these notes the term Basic will mean the specific Malvern Zetasizer version of the language. -
Page 18: Building Blocks Of Programs
MAN0179 The use of line numbers with tests to change the order of execution. Basic is not case sensitive. That is, you can use upper and lower case characters in any combination. Spaces are not significant. Thus, RectWidth = Val ( X$ ) RectWidth = Val ( X$ ) are equivalent. -
Page 19: Commands And Functions
Introduction to Zetasizer basic MAN 0179 2.3 Commands and functions Commands may perform a variety of actions depending on the choice made by additional parameters. They may also modify those actions with further parameters. Functions may be similarly modified. The full list of all functions and commands (over 200 items and all their variant parameters) will not be described in detail here. -
Page 20: Arrays
MAN0179 There is space for 50 user variables in any program. An error is reported if this number is exceeded. If one program calls another the variables in the calling program are not accessible from the called program (but see below for arrays). It is good practice to choose variable names which describe the values they will contain. -
Page 21: Expressions And Operators
Introduction to Zetasizer basic MAN 0179 Array elements may be used in any place in which a simple variable is used. For example: Dim X ( 5 ), Y ( 5 ) For i = 0 To 5 A$ = InputBox$ ( “ ”, “ ”, “1.0" ) X ( i ) = Val ( A$ ) Y ( i ) = Log10 ( X ( i ) ) Next... -

Otherwise the command is executed. example: If CountsPerSec <...

Page 27: Functions - A Review
Introduction to Zetasizer basic MAN 0179 A program may also be run automatically when the Zetasizer software is first started. This may be used, for example, to automatically start a measurement sequence. See Control-Assign Program in the Software Reference Manual for more information. 2.9 Functions - a review There are over 220 functions available but they will not all be dealt with individually here. -

Try reducing the number you use using expressions and not calculating intermediate values as variables. For example: X = I + 1 Y = 10 * X Z = J...
- Page 32 MAN0179 End if Divide by Zero An attempt has been made to divide by an expression which evaluates to zero. This is often caused by mis-spelling a variable name or forgetting to assign a value. For example: NewX = I + 3 Y = 1 / NwX Math domain error You have used a Math function with an illegal expression.

Page 35: Introduction
Designing pages and reports MAN 0179 3.1 Introduction The standard tables and reports provided with the Zetasizer system are produced by various page and report programs. A page (or report) program is a “script” written in Malvern Page Description Language (PDL), which allows selection of the display items, text, graphics, and font and format of the displayed text. - Page 36 MAN0179 page or report. This name appears in the View menu when the page is assigned and when the Info button is pressed in the Setup - Table dialogue. During editing your program you can use the Run button in the editor to test the program, the table or report you are editing will be shown on screen.

Page 117: Exchange Of Data With Other Programs
Advanced Features MAN 0179 5.1 Exchange of Data with other programs Two basic methods are available to the user. DDE (dynamic data exchange) is a message passing system which can be used to set up a link to other applications This is essentially a Macro program in the PCS program which is run to transmit the necessary data. - Page 118 MAN0179 We show such an example below for communication with the spreadsheet program Excel. Valid items for Excel include strings of the form “R1C1", which addresses row 1 column 1 in a spreadsheet document. In the example we make use of the Macro language string handling capability to randomly access the first two columns of the target spreadsheet.

Advanced Features MAN 0179 5.1.2 Transferring data by File In the example listed below (PCOEX.PCM) a program has been written to dump the major parameters of a PCS correlation experiment to disk. This program is named PCOEX by analogy to a command (PCO) in previous DOS based Malvern software which ‘put the correlogram’ to a specified file or device, for processing by other programs. - Page 120 MAN0179 524296 520346 516587 512896 509013 505311 503627 499345 495914 541193 524698 509311 496582 485082 474354 464848 457085 450052 444154 438557 433481 428824 ————————————— 395565 395493 395372 394850 427010 400173 396249 395156 394904 394946 394994 395353 395009 395060 394969 394878 394742 395195 395048...

Page 121: Transferring Data By Macro Program Via The Clipboard
Advanced Features MAN 0179 A simple variant of this program could readily be used to output results rather than data. Please refer to one of the supplied ‘page programs’ (sizerep1, zetarep1) that display results. The functions sizes intensity that return size classes and contents could easily be used with print file using rather than... -
Page 122: Remote Control
MAN0179 keyboard/mouse again. Alternately a startup program might be in control for the entire session, possibly responding to remotely signalled DDE events (running with the Autosampler Scheduler programme is a case in point). A program might run in a completely stand alone way, performing a series of processing steps, then terminate using the Exit command.
