7... HYPERNET™ I CON BASED PROGRAMMING
Icon Assortment
A complete reference listing of all of the icons available within HyperWare is included in the Master Icon Listing in Appendix A. Details on Configuration, applications, and proper usage are described.
| Global Icon |
| |
| One special icon that is included in every Program Net is called the Global | ||
| icon. Within the Global icon’s Configuration dialog are options for various | ||
| global Program Net options. These options include Program Net Name, | ||
| memory utilization mode, clock resolution, and modem paramteres. The | ||
Figure 7... - | operation of this icon should be reviewed in the Master Icon Reference in | ||
12: Global | Appendix A before attempting to construct a Program Net. | ||

| Making Connections Between Icons |
| |
| Lines are used within a Program Net to indicate the flow of signals between | ||
| icons. (See Figure 7... |
| |
| Signal Types |
| |
| Three types of signals can be communicated between icons in a | ||
| Program Net. The three signal types are differentiated by color and | ||
| their different functions follow: |
| |
| DATA (RED) |
| |
| Numerical values are transmitted from icon to icon via Data type | ||
| signal connections. HyperNet allows Data connections to be | ||
| made ONLY between Data terminals on icons to preclude | ||
| mismatching of signal types. |

| LOGIC (GREEN) |
| |
| True / False values are transmitted from icon to icon via Logic | ||
| type signal connections. Logic signals have only two states. As | ||
| with the other signal types, HyperNet only allows Logic signals to | ||
| be connected to Logic type terminals on icons. |
