I'm going to ask yet another dumb question - Unidata 6.1.4 on Solaris (soon to
be 7.1.x).
I'm selecting a bunch of records and then outputting data from them into an
ascii file in _HOLD_. If I open a sequential file, write the data
line-by-line (WRITESEQF) and close the file, it takes about 5 minutes. If I
save the data in a @FM delimited record and then write the record out at the
end, it takes about 3 seconds.
I'm well aware that writing sequentially is doing a whole lot more disk I/O
but I can't believe the difference in speed. Are their any subtleties other
than disk I/O? I seem to recall some discussion about seq files and
maintaining the pointer of where the current position in the file, but I'm
foggy on these topics...
