Can anyone explain why my code fails with "geoprocessing object not iterable" in 9.3 but works in 10. Are there some compatibility issues going on? I wrote the python code in 10 but made sure not to make any calls to arcpy.
I invoked, gp = arcgisscripting.create(9.3)

My understanding is before 9.3, python didn't use 'real' lists, so calling list methods would obviously fail. Is that wrong? Is 9.3 not able to use list methods?

The following code, I believe, is where the problem is...I think??
# function to return appropriate 3.0 feature class for given 2.6 feature class # and it returns the name of the fieldname, FC_26_name def which30(two6ftrcls):      two6FC = two6ftrcls     whereclause = "Two6FCs = '" + two6FC + "'"     gp.AddMessage("whereclause is " +whereclause)     crosswalk = ShellPath + "/Two630FC_IDPKxwalk.dbf"     # The variables row and rows are initially set to None, so that they     #  can be deleted in the finally block regardless of where (or if)     #  script fails.     row, rows = None, None     Three0ftrlst = []     FC_26namelst = []     rows = gp.SearchCursor(crosswalk,whereclause)     row =     if (row == None):         gp.AddMessage("check the Two630FC_IDPKxwalk.dbf table for Two6FCs -->" +two6FC)     elif (row != None):        rows = gp.SearchCursor(crosswalk,whereclause)        for row in rows:            if not row.isNull("Three0FCs"):               Three0ftr=row.getValue("Three0FCs")               Three0ftrlst.append(str(Three0ftr))               FC_26name = row.getValue("FC_26")               FC_26namelst.append(str(FC_26name))      if row: del row     if rows: del rows      return Three0ftrlst, FC_26namelst
