<H2>Numerical Electromagnetics Code-2</H2>
The implementation of the NEC-2 code in this package accepts free
form input with fields separated by white space instead of rigid
fixed format input used in older versions.
<p>
The rules for the free format input are as follows
<table>
<tr>
<td>1) First two columns must contain the type of CARD e.g. CE</td></tr>
<tr>
<td>2) Subsequent columns must be separated by either, at least</td></tr>
one blank space, or a comma.</tr>
<tr>
<td>3) Scientific notation can be used for specifiying REAL
valued quanties.</td></tr>
<td>4) Decimal points may be omitted or used as desired. For example
<table>
<tr><td>(Integer Expected)</td><td>3232.</td><td>translates to 3232</td></tr>
<tr><td>(Real Expected)</td><td>1213</td><td>translates to 1213.</td></tr>
<tr><td>(Real Expected)</td><td>12E-3</td><td> translates to 12.E-3</td>
</tr>
</table>
</tr>
</table>

The original NEC-2 code was documented by a three volume set 
of manuals, the first describing the theory of the EFIE and MFIE
boundary element method with point collocation used by NEC-2 (commonly 
called `method of moments').  The second volume provides a 
typescript listing of the original fortran code.  
The third volume, the user manual is the basis for the 
HTML format manual included within this distribution.
