|
|
<P>Print the list of arguments as a line of text to the screen and/or
|
|
|
|
|
logfile. If variables are included in the arguments, they will be
|
2007-02-10 05:37:30 +08:00
|
|
|
evaluated and their current values printed. Note that if variables
|
|
|
|
|
are included, the print string should not be enclosed in double
|
|
|
|
|
quotes, else it will prevent the variables from being evaluated.
|
|
|
|
|
</P>
|
|
|
|
|
<P>If you want the print command to be executed multiple times (with
|
|
|
|
|
changing variable values), there are 3 options. First, consider using
|
|
|
|
|
the <A HREF = "fix_print.html">fix print</A> command, which will invoke a print
|
|
|
|
|
periodically during a simulation. Second, the print command can be
|
|
|
|
|
used as an argument to the <I>every</I> option of the <A HREF = "run.html">run</A>
|
|
|
|
|
command. Third, the print command could appear in a section of the
|
|
|
|
|
input script that is looped over (see the <A HREF = "jump.html">jump</A> command).
|
|
|
|
|
</P>
|
|
|
|
|
<P>See the <A HREF = "variable.html">variable</A> command for a description of <I>equal</I>
|
|
|
|
|
style variables which are typically the most useful ones to use with
|
|
|
|
|
the print command. Equal-style variables can calculate complex
|
|
|
|
|
formulas involving atom and group properties, mathematical operations,
|
|
|
|
|
other variables, etc.
