should be in the directory “D:\REFFIT” and the macro file “MACRO1.RFS” should be in the currently selected directory. There are several ways to launch the RefFIT program with a script name. The most universal one (though not the most handy) is to create a batch file, called, e.g., “MACRO1.BAT”, which contains only one command line “D:\REFFIT\REFFIT.EXE MACRO1.RFS”. It can be done using the same editor program, like Notepad (Figure 4-21). The execution of “MACRO1.BAT” (e.g., by clicking on it in the Windows Explorer) will have the desired effect. Figure 4-21 The batch file to start macro “MACRO1.RFS”. Scripts can be called more comfortably by just double-clicking on the icons of their files. For that one should associate the file extension “RFS” with the executable “REFFIT.EXE”. It can be done, for instance, in the standard Windows Explorer program by clicking on a macro file with the right mouse button, selecting item “Open With”→”Choose program” and then specifying the actual path to “REFFIT.EXE”. 4.11.2. Macro syntax The RefFIT macro syntax is extremely simple. Macro scripts consist of commands, separated by semicolon “;”. It is a good idea (although not imperative) to write each command on a separate line. Commands correspond to actions done by the mouse or the keyboard in the application windows. The command syntax is as follows: “CommandName(Par1 = Value1, Par2 = Value2, …);” The CommandName identifies the command. “Par1”, “Par2” etc. are the names of parameters; “Value1”, “Value2” etc. are their values. The parameters should be separated by commas “,”. The set of parameters depends, of course, on the command. In some cases certain parameters might be omitted. Even if no parameters are set in the command, the command name must be followed by empty brackets “()”. The sequence of parameters in brackets does not matter. The parameters can be of integer, double or text type. The integer parameter value can be any integer number, e.g., 10. The double parameter value can be any double (floating point) number, e.g., 1.23E-4. The text parameter value should be a text string, enclosed in parentheses “…”, e.g., “CONDUCTIVITY”. Any command preceded by the “#” character is ignored by the macro interpreter. This can be used to put text comments into the macro, or temporarily ‘comment out’ some commands. Guide to RefFIT Page 80
Before a macro is actually executed, it is first translated by the macro interpreter. If the interpreter finds any kind of error, the execution does not start. Unfortunately, at this moment the interpreter is not programmed to make any error report. If a macro does not run, the easiest way to localize the error is to comment out potentially erroneous commands one by one and try the macro again. 4.11.3. General macro commands Command name: MainWindow Description: Moves, resizes and renames the main application window. Parameters: Name Type Description What if omitted XPos Integer Horizontal position of the left side (in Window is neither screen pixels) moved nor resized YPos Integer Vertical position of the top side (in Window is neither screen pixels) moved nor resized Width Integer Window width (in screen pixels) The window is moved but the width is not changed Height Integer Window height (in screen pixels) The window is moved but the height is not changed Title Text Window title The window title is not changed Command name: Wait Description: makes sure that the screen (i.e., parameters and model curves) is fully updated to reflect the last parameter changes and then waits the specified amount of time. Note: this is a ‘technical’ command, which has absolutely no influence on the data and fitting process. Parameters: Name Type Description What if omitted Time Integer The extra time to wait (in Assumed to be 0 milliseconds) Command name: Suspend Description: suspends the macro execution and shows a “Suspend” window (Figure 4-22), which allows a user to choose whether to continue or stop macro execution. Note: It is useful, when the macro works in a cycle and the fitting match has to be visually verified on each step of the cycle. Guide to RefFIT Page 81
