Format

Dependency tags can take one of three start formats, an otherwise format, and also a single end format:

Output-when-match:
(_dNNNN+xxxxxxxxxx)
If comparison string xxxxxxxxxx is the same as the screen data at screen offset NNNN, all the data between the start and end dependency tags is written to the browser (including any other Web Option tags, which is processed as normal). The lines containing the start and end tags themselves are not written.
Skip-when-match
```
(_dNNNN-xxxxxxxxxx)
```
If comparison string xxxxxxxxxx is the same as the screen data at screen offset NNNN, none of the data between the start and end dependency tags are written to the browser. The lines containing the start and end tags themselves are not written.
Output-when-field:
```
(_dNNNNI)
```
If an input field exists on the screen at offset NNNN (whether or not it contains data), all the data between the start and end dependency tags are written to the browser. The lines containing the start and end tags themselves are not written.
Otherwise tag:
```
(_dNNNNX)
```
If a start tag of any type has been encountered with screen offset NNNN specified and that tag was not fulfilled, then the lines between this tag and the end-tag are output.
End tag:
```
(_dNNNN)
```

The end-tag ends a section of dependent skeleton.
