<DIV>try this:</DIV>
<DIV>'define x = (P.2/T+10)'</DIV>
<DIV>'d x'</DIV>
<DIV> </DIV>
<DIV>I believe the issue is related to not specifying the fact that two files are open at the same time. In this case, you have two open files (T and P) that need to be specified as one and two. The above script example assumes that T was opened as the first file and P as the second. All open files after the first one need to be specified: file, file.2, file.3, etc....</DIV>
<DIV>Does this help?<BR> </DIV>
