PvmGet
</h2>

Receives data from PVM.

<p><p>

<h3>
Syntax:
</h3>
<pre>L := PvmGet();</pre>

<p>

<table>
<tr>
<td>List</td>
<td><pre>  L  </pre></td>
<td></td>
</tr>
</table>

<p>


<h3>
Description:
</h3>
If there is (valid) data <tt> PvmGet</tt> will receive one (complete) item,
otherwise the return
value is false. If it successfully receives data it will return a list
containing a (small) integer as first entry as a flag. If flag
equals 1 the other list entries are (exactly) as sent e.g. by PvmSend.
\par If flag equals
2 this is send by Error(fmt) on a slave. The second entry will contain
the hostname, the third the output of Error(fmt).
\par If flag equals 4 the data comes from an ordenary Print() on the slave.
The second parameter will be the hostname, the third the data string.
\par Attention, it is possible to send arbitrary data with flag of 2 and 4
using <tt> PvmSlavePrint</tt> or <tt> PvmSlaveError</tt>. Data sent this way may not
contain the hostname.
\par In the examples given below we will NOT describe how to set up the
pvm-network. Lines beginning with <tt> slave></tt> indicate commands executed
on the slave. They will not work an the master.
