We can then see the contents of any variables using the Variables pane. Whenever program flow reaches a breakpoint the program will pause at that point. To stop the execution of a program at any given location, insert a breakpoint at that spot using the Edit - Breakpoints command. The Manifold debugger takes advantage of features built into Microsoft's Active X scripting environment to provide sophisticated, professional-class debugging capability.

Adding extra statements is slow and there is always the risk of forgetting some debugging statements within production code or of inadvertently changing the execution of a program by the debugging code.Ī much faster way to debug code is to use a debugger like the Manifold debugger.

For example, if we are not sure that the program reaches a particular function correctly we might insert a few lines of code that when that function is reached will print out some text like 'Got to AddNextRecord() OK' or which might print out the values of variables that we suspect are being mishandled with printed output like 'Executing LoopRecord with RecordNum = 36'.Īs any professional programmer knows, it's really tedious to lard up one's code with lots of extra debugging statements. The traditional way of finding out what a program is doing while it is executing is to insert additional lines of code for debugging purposes. To track down any problems we have to know what is going on inside the program as it executes. More frequently a new program of any complexity will not work quite right the first time or it will exhibit unexpected behavior (a 'bug') when it functions. If it works the first time without any flaws we're somewhat surprised but happy. Traditionally, we can write a program that consists of one or more functions. To understand what a debugger does, let's take a moment to consider the old-fashioned way of writing and debugging programs. At any time when a progam is paused or stopped we can see what are the values of any variables or other information we would like to know. When a script is running under the control of a debugger it may be started and stopped, paused, re-started at a different location in the code, automatically stopped whenever it reaches a marked breakpoint and so on. Run a script under control of the debugger.Ī debugger is a specialized execution environment within which programs (like Manifold scripts) may be run in a controlled way that helps debug those programs. Commands will be enabled in the debugger toolbar as make sense given the execution state of the script. The debugger helps us develop and debug scripts in the scripting language of our choice. If the Debugger is installed, when a script has the focus the tools toolbar will have debugger commands enabled. All regular runs of Active Column functions are done without the debugger. Doing this runs the function, which will generate values for the active column in the context of the clicked cell. To debug an Active Column script, right click on an Active Column cell and choose Run under Debugger from the pop up menu. Scripts associated with Active Columns can also run in the debugger. The Edit - Breakpoints command is used to set breakpoints for use with the debugger. The debugger works together with the Call Stack, Variables and Watches panes and is controlled by the Tools toolbar configured with debugger commands when a script is open. Debugger commands, including the project pane's Run under Debugger button, will automatically be disabled if a script window uses. NET are not supported by the debugger and should be debugged using the Microsoft console debugger that is part of the free. Note that at the present writing the ActiveState PERL and Python scripting languages do not support Microsoft debugging calls and so may not be used with the debugger even though they may be used for scripting. The debugger works with VBScript, JScript and any other ActiveX scripting engine that supports Microsoft debugging calls. NET script under the debugger will display an error message. NET languages (which, in addition to ActiveX languages also may be used for scripting within Manifold).NET languages have their own debugging framework. The Manifold debugger does not work with. See the 32-bit and 64-bit Manifold Editions topic when running 64-bit Manifold System editions. The Manifold debugger requires installation of Microsoft facilities that support debugging of ActiveX scripts (see below), which are not available in 64-bit mode in Windows.

The debugger is not available when Manifold is running in 64-bit mode in 64-bit Windows systems, nor at the present writing is it available in Vista. The Manifold Debugger provides an integrated debugger for use with scripting in Manifold System running in 32-bit mode.
