The command <em>vecdim</em> changes the vector dimension from 4 to an arbitrary 

integer or symbol. Used in high-energy physics calculations.

<em>vecdim</em>&lt;dimension&gt; 
<P>
<P>
<P>
&lt;dimension&gt; must be either an integer or a valid scalar identifier that 
does not have a floating-point value.

<P>
The 
<A HREF=r37_0410.html>eps</A> operator and the gamma_5 
symbol (<em>A</em>) are not properly defined in anything except four 
dimensions and will print an error message if you use them that way. The 
other high-energy physics operators should work without problem.
