(i) What’s in an item file?
Each and every item file has to start with a header line. This sets various parameters for the experiment. An example is shown below:
<azk> <cr> <fd 17> <d 169> <t 2500> <vm 1024, 768, 768, 16, 0> <id PIO12> <id keyboard> <nfb> <dbc 255255255> <dwc 0>
This looks scary, but isn’t when broken down piece by piece.
A few of these keywords will go in more or less every file that you’ll use. I’ll explain most of these, but there’s some moredocumentation in the DMDX help files.
