$ KCAP/TRACK/REOPEN /SPAN = minutes
                       /NOSPAN

   Specifies the approximate time period which should elapse before
   a new version of a terminal-logging file should be started, when
   /REOPEN is in effect.

   Use /NOSPAN to specify that any default /SPAN value should
   be ignored.

   The default value for this qualifier is taken from the logical
   name KCAP$SPAN.

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

   The number of minutes can contain a decimal point. The minimum
   acceptable value is 1 minute.
