Hi Vijay, <div><br></div><div>The TDEF has to be specified in the following form: </div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif; font-size: 13px; "><a name="TDEF"><b>TDEF</b> <i>tnum</i> LINEAR <i>start increment</i></a></span></div>
<div><font class="Apple-style-span" face="Arial, Helvetica, sans-serif"><i><br></i></font></div><div><a name="TDEF"></a><font class="Apple-style-span" face="Arial, Helvetica, sans-serif"><i><span class="Apple-style-span" style="font-style: normal;">So the easiest way to understand what each argument represent is to look at an example... </span></i></font></div>
<div><font class="Apple-style-span" face="Arial, Helvetica, sans-serif"><i><span class="Apple-style-span" style="font-style: normal;"><br></span></i></font></div><div><font class="Apple-style-span" face="Arial, Helvetica, sans-serif"><i><span class="Apple-style-span" style="font-style: normal;"><span class="Apple-style-span" style="font-size: 13px; "><table width="100%" border="0" cellpadding="0" cellspacing="0" class="plaintext" style="font-family: Arial, Helvetica, sans-serif; font-size: 10pt; font-style: normal; font-weight: normal; ">
<tbody><tr><td>TDEF</td><td align="right">12</td><td align="center">LINEAR</td><td>1jan2000 1mo</td></tr></tbody></table></span></span></i></font><br><div class="gmail_quote">So in this example, we have 12 data records where the 1st record is of 1st Jan 2000. The increment is 1 month, so that means the 2nd data record is one month after the first time step (i.e. 1st Feb 2000). </div>
<div class="gmail_quote">Because it is LINEAR, it means every time step is a constant increment to the previous time step. </div><div class="gmail_quote"><br></div><div class="gmail_quote">Change each argument to fit your data.
