Conditional text in LaTeX??
Ken Poppleton
Is there a macro package which will work with LaTeX to allow
conditionally included text in a LaTeX document? Or what would the
TeX code be to perform this task? What I would like
is a set of LaTeX commands of the form...
\newconditional{conditionalName}[value]
which would define a new conditional variable 'conditionaName' set to the
optional value. Value would be either \True or \False
\setconditional{conditionalName}{value}
Set a conditional to a value. Value could be either \True or \False.
\begin{conditionalName}
some latex text...
\end{conditionalName}
This would only include the text between the \begin and \end if the
conditional is set to \True.
I currently do not understand enough of raw TeX to create this my self so
any assistance would be helpful...
Thanks in advance

The ifthen package does this. Include in your file the line
\usepackage{ifthen}
Then set your variable to true or false by
\newcommand{\condition}{true} or \newcommand{\condition}{false}.
Then you can use the following statement:
\ifthenelse{\equal{\condition}{true}}{
blah-blah %this is printed iff \condition is set to true
}
{
another blah-blah %this is printed otherwise
}
Good luck

Here's a portion of a bibliography that typesets journal titles
abbreviated or in full depending on the value of a flag. Maybe
something like this is what you had in mind?
