I have a macro to read in the a comma seperated value (CSV) file and
set the data into a named range. The file format is
<range_name,<numeric value. The problem is that the macro takes about
8 minutes to read 34000 records and seems to gradually slow down.
This would lead me to believe I have a memory leak of some kind. Most
of the time is split evenly between two functions
1) getRangeAddress2() to get the worksheet name range
2) Range(ra) = dprecord(1) to set the actual range value.

Any suggestions?
