<p class="label"><b>Remarks</b></p>
<p>The <b>set_verbose</b> function sets the verbose level.<br>
lp_solve reports information back to the user. How much information is reported
depends on the verbose level. The default verbose level is NORMAL (4).
lp_solve determines how verbose a given message is. For example
specifying a wrong row/column index values is considered as a SEVERE error. <i>verbose</i>
determines how much of the lp_solve message are reported. All messages equal to
and below the set level are reported.<br>
The default reporting device is the console screen. It is possible to set a
used defined reporting routine via <A href="put_logfunc.htm">put_logfunc</A>.

<p class="label"><b>Example</b></p>

{
lprec *lp;
/* Create a new LP model */
lp = make_lp(0, 0);
if(lp == NULL) {
fprintf(stderr, "Unable to create new LP model\n");
