Duxbury Systems has been working with an English translation of an earlier edition of this standard.

#### Data Entry Considerations

To use the Russian mathematics translator, you must use the **math** style in DBT to surround the passages of mathematics. Depending on your data entry method, this may be done for you. For example, all LaTeX files show the distinction between text mode and math mode (also called technical notation). As DBT imports the LaTeX file into DBT, it applies the **math** style to the technical notation for you, simplifying the process.

#### Working Directly in DBT

To enter your math when working directly in DBT, for a section consisting mostly of technical notation, first, highlight the entire section, then press F8 to apply a style and select **math** for the style. If there is a text passage within that section that would not work well in a math translator, you can apply to it the style, **math-TextInMath**. Note that both the start and end style markers of a **math-TextInMath** passage must lie entirely within the **math** style. Failure to do so may cause DBT to get lost in the translation (i.e. to do unexpected things).

#### More About Working with LaTeX Files

When you open a LaTeX file in DBT, DBT's math importer assigns the DBT style math wherever the LaTeX is in math mode, and the DBT style **math-TextInMath** wherever the LaTeX is *text* within math mode. For numbers and other mathematical symbols written in text mode in a LaTeX file, the **math** style will not be applied automatically. You may need to do that manually.

There are many ways to create LaTeX files. An example is using the program InftyReader on scanned material. Other possible programs are TeXnicCenter, TeXStudio, LyX, and more.
