Counters and Length parameters

Next: Document and page organisation Up: Document structure Previous: Document structure

Counters :- L^ATEX maintains many counter variables (e.g. page, part, equation, footnote, chapter, paragraph, section, subsection, subsubsection, enumi, etc). You can set these counters yourself. Some examples:-
```
\setcounter{page}{0}
\addtocounter{chapter}{2}
```
Length Parameters :- L^ATEX accepts the following units of length: in, cm, mm, pt (there are 72.27 pts to an inch), em (width of an M), ex (height of an x). These units can be used to set the values of length variables using \setlength. For example,
```
\setlength{\parindent}{0in}
```
sets to zero the amount by which the first line of a paragraph is indented. Other useful length parameters are:-
parskip:-
determines the gap between paragraphs.
baselineskip:-
determines the usual distance from the bottom of one line to the bottom of the next. You can adjust this to produce double spacing, but a better way, which takes a stretch factor as argument is to use \linespread. For instance before \begin{document} you can do
```
\linespread{1.6}
```
to get doublespacing through your document. The setspace package offers more options.
