General ⇒ Make a reference to a portion of text

[GommaFleX]

Hi, i wonder if there is a command that allows to do this. I have a "long portion of text"(it's an algorithm) that i want to move frequently in the paragraph. For example:
Initially i have

Code: Select all

some text
Long portion of text
some other text

then i want to move the "long portion of text":

Code: Select all

Long portion of text
some text
some other text

That's unhandy!
I want to do something like this:

Code: Select all

some text
\include{longportionoftext}
some other text

...

\portionoftext{longportionoftext}{
Long portion of text
}

Is there a way to do something like this?

You can put it in a separate file, e.g.

Code: Select all

% main.tex or similar name
some text
\input{longtext}
some other text

% longtext.tex
Long portion of text

Another way (and what I would probably do unless it is a LOT of text) is to define a new command:

Code: Select all

\newcommand{\longtext}{%
Long portion of text
which goes on for some time
and even

has multiple paragraphs.}
...
\begin{document}
...
some text
\longtext
some other text
