DmDX 4.0

New Features You Need to Know About.
On-line Help File. First, there is now an on-line Help file, accessed from the DMDX dialogue box. In time, there will also be supplementary notes written as an .html document.
TimeDX. DMDX will not run until you have run TimeDX. This program is designed to establish the properties of your machine (graphics resolution, refresh rates, type of sound card, presence of PIO card, etc.), and to record these in the Windows Registry, so that DMDX will know what kind of machine it is running on. TimeDX also has its own Help file.
Standard file formats. DMDX uses standard Windows formats: .bmp files for graphics, .wav files for sound files. In addition, digital video is also supported (including the ability to measure RTs to critical frames within such displays). Streaming video and/or audio can also be used for off-line situations, such as presentation of contexts, instructions, etc.
Output Files. The default output mode is now an .AZK file (a text file listing item number and RT in the order presented to the subject, plus warning messages about display timing errors). The assumption is that users will feed this output into an application such as Excel for future processing. However, users can still use the .dtp output option.
Input File. The old .itm file has been replaced by an .rtf (rich text) file. These can be produced by any Microsoft Word for Windows program, also by Write and WordPad.
WYSIWYG. Manipulations of the appearance of text within the .rtf file will be transferred to DMDX. So, if the text appears as red in the .rtf file, it will appear as red on the display screen. If it is in 10 point in the .rtf file, it will be 10 point on the screen.
Switches and Parameters. Instead of having a single character as the first element of a switch or parameter, DMDX allows for any number of characters, e.g., . Note the use of angled brackets. These are referred to as "Keywords" in the Help files, and a complete listing is available there.
