In contrast to the previous UDO version UDO Release 6 will save a LaTeX preamble automatically for LaTeX 2.09 or LaTeX2e.
If you don't like the automatically generated preambles you tell UDO not to save them by using the switch !no_preamble [tex] inside the preamble of your UDO source file.
In this case you can enter the special LaTeX commands at the beginning of the UDO source file with !tex or a raw environment.
The following example shows how you can do this:
!code_iso !no_preamble [tex] # Uncomment the following line for LaTeX 2.09 # !tex \documentstyle[12pt]{article} # Uncomment the following lines for LaTeX2e !tex_2e !tex \documentclass[12pt,a4paper] !tex \usepackage{a4} !begin_document !node Example This example uses a userdefined (!LaTeX) preamble. !end_document
