    5) diskox - trace0 didn't work on Intel
ver 2008.4 (20 May 2008)
    1) diskin, diskio - podisc(lun, 0, 0 ) is bad practice and didn't work.
    2) diskio, seg2in - That change made relative addressing bad.
    3) plot (tlann.c) - Use absolute value of time for negative time.
    5) diskio - still problems with podisc
    6) segddin - water depth was not going into word 54 (needed by nmo/vtrkwb)
    7) segddin - extended file number was bad
    8) diskio - Do the podisc as set to 0 followed by 4 set_cur (allows 8GB)
