ABOUT DATA...
Each file contains five columns of data:
YEARorYEARCLASS SSB REC LAND FRPL
YEARorYEARCLASS refers to the year for SSB, LAND, and FRPL.
It refers to the yearclass for REC.
All four digits are used (e.g. 1984 rather than 84).
SSB is the spawning stock biomass in that year.
REC is the recruitment for that yearclass.
LAND is the landings for that year.
FRPL is the fishing mortality for that year.
Note that a dot (.) denotes a missing value, as in the .doc files.
