^^PLTDAT\\ INFORMATION
.S 3
 ^^PLTDAT.DAT\\ IS A FILE CREATED BY ^^SYSREP\\ WHICH CONTAINS
VARIOUS INFORMATION ABOUT THE SYSTEM TAKEN AT HALF HOUR
POLLING INTERVALS (NOTE: *.^^WEK\\ FILES ARE IDENTICAL IN FORMAT
TO ^^PLTDAT.DAT\\).
^THERE ARE 49 POSSIBLE DATA POINTS,
STARTING AND ENDING AT MIDNIGHT. ^THE FILE IS WRITTEN IN
IMAGE MODE AND ESSENTIALLY CONTAINS THREE ARRAYS; ^^PLTST,
PLT\\, AND ^^PLTD\\. ^^PLTST\\ CONTAINS GENERAL DATA FOR THE
ENTIRE PERIOD AND IS 30 WORDS LONG. ^^PLT\\ IS DIMENSIONED TO
CONTAIN 20 DIFFERENT STATISTICS FOR THE 49 POSSIBLE DATA POINTS.
^^PLTD\\ CONTAINS INFORMATION ABOUT DISKS. ^IT IS INDEXED
BY DISK NUMBER (1-5 AT ^^MCRC\\), ITEM NUMBER AND DATA
POINT. ^BECAUSE OF A CRASH OR OTHER REASONS, A DATA POINT
MIGHT NOT OCCUR, AN EMPTY DATA POINT CONTAINS -2. ^BELOW
IS A SAMPLE ^FORTRAN-10 PROGRAM TO READ ^^PLTDAT.DAT\\ AND
PUT THE DATA IN THE RIGHT ARRAYS:
