Images aren't displayed centred?

Get the current ST-Guide version. Since Release 15 the ST-Guide can center images itself.

How does UDO create the title page and the table of contents?

The title page and the table of contents are displayed inside a special node. The title page node is named Title. The node that contains the table of contents is named Main.

To let the ST-Guide display the first page of the hypertext (this will be the title page in most cases) just pass the name of the hypertext. To let the ST-Guide display the table of contents pass the node name Main. How you can call the ST-Guide from programs you can read in the HCP hypertext.

How can I suppress the headlines?

UDO prints a headline in every page by default. The headline contains the current node name and the title of the hypertext. The headline will be displayed underlined.

Using the switch !no_headlines [stg] inside the preamble you tell UDO not to create these headlines.

How does UDO insert hypertext links?

UDO just insert hypertext links when you use (!link) and (!xlink). All the other hypertext links will be inserted by the HCP.

How does UDO convert labels?

The UDO command !label will be replaced by the HCP command @symbol ari. You have to check yourself if there's a node or a label existing with the same name.

How can I make popup nodes?

Using the !pnode and the familiar commands you can tell the ST-Guide to display the contents of the node inside a dialog box instead of a window.

But you have to remember that text inside a popup node may have up to 12 lines of text with 60 characters per line only. Furthermore no images and links are allowed inside a popup node.

UDO breaks line after 60 characters but it doesn't print an error message if you use more than 12 lines, images or links inside a popup node.

There's always an empty line at the end of a popup node, why?

UDO reads in the source file line by line. If an empty line appears UDO will print the last paragraph and an empty line for separation.

UDO does the same when printing the text of a popup node. The problem cannot be solved, I'm sorry.

Some cells of my table are too wide, why?

The ST-Guide has a built-in italic correction which is active in tables, too. Unfortunately the ST-Guide adds a blank when it reads an italic-off command. This problem can only be solved by Holger Weets, the author of ST-Guide.

Thus you shouldn't use italic text inside tables when converting to ST-Guide until Holger doesn't offer a command for disabling the italic correction.

The HCP prints the error message please add..., why?

If the HCP prints the error message please add a @subject-command to this text at the end of converting the STG file you have forgotten to insert a line like the following one at the beginning of your UDO source file:

!stg @subject "Documentation/Utilities"
How can i create a user-defined title page for ST-Guide?

If you don't like the layout of the title page UDO will make with !maketitle you can make your own title page with some commands:

The following example shows how to make your own title page but only for the ST-Guide. It uses a hidden node that contains the word Contents at the end. The ST-Guide will insert a link to the table of contents due to this word.

!docinfo [program] Title pages with UDO


!ifndest [stg]



!node* Title

The hypertext to ""Hello, World!"" (!nl)
Version 8.4

written by

Ford Prefect





!node The first chapter
This is the first chapter.

!node Bye bye
Stop it, now!

Why it is better not to use justified text?

Why that? you might ask. Well, Martin Osieka has written a program called Hyperion for the Apple Macintosh that can display ST-Guide hypertexts.

In contrast to ST-Guide Hyperion can display hypertexts with proportional fonts but only if you don't use justified text.

Thus you should don't use the justification if you want that Macintosh users shall also read your hypertext without any problems.

If you have written a system specific hypertext that is only interesting for Atari users you can use justification without any doubts.
