<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">I just started to Type536 for a linear parabolic concentrating solar collector and have to change the IAM data file. I
found the necessary information in the Mathematical References. I use not 10 but 7 values. The problems started when I tried to include this data file.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">There were error messages about wrong number of data points or that die unit number is wrong. So I had a look at the source
code because I had the feeling that there is something mixed up.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">And this is what I found:<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">In the Proforma for Type536 Parameter 17 is for Number of Transverse IAM Data Points and Parameter 18 for Number of Longitudinal
IAM Data Points. Parameter 19 is the unit number for the data file. But in the source code (line 214 to 216) Parameter 17 is the unit number and 18 and 19 for the numbers of the IAM values. I am not really sure so maybe someone can have a look at it.<o:p></o:p></span></p>
