$ KCAP/TRACK/REOPEN /MIN_REOPEN = blocks
                       /NOMIN_REOPEN

   Specifies the minimum number of blocks to which a terminal-
   logging file must grow before a new version of the log file is
   started, when /REOPEN is in effect.

   Use /NOMIN_REOPEN to specify that any default /MIN_REOPEN value
   should be ignored.

   The default value for /MIN_REOPEN is taken from the logical
   KCAP$MIN_REOPEN, usually defined by KCAP_DEFAULTS.COM.

   Example: $ KCAP/TRACK/REOPEN/MIN_REOPEN=10

   /MIN_REOPEN is ignored for reopens done as a result of
   a /TIME_OF_DAY specification.
