Rufus Peabody <[email protected]>:
I am guessing there are a number of errors in that code, but I can't
see what is causing the error message you got.  Try
 set trace on
 set traced 2
and run again to see where the error is thrown.

Before you do though--check this line
 local mark=mark
which sets the value of local mark to the value of the variable mark
in obs#1 in every iteration.  Is that what you meant to do?

Also, the condition
  if tm_gmid_yr<=tm_gmid_yr+7 & tm_gmid_yr>=tm_gmid_yr-7
is unlikely to be what you wanted, since it is always true.
