         CLOCK_MSEC     =  FALSE

COMMENT ^

   PRI_TIMER      Priority of the timer task. Normally higher than any
                  other task in the system.
                  The default is 0xf000.

   PRI_STD        standard priority of user tasks (arbitrary), for use
                  in user programs.
                  The default is 100.

   PRI_INT8       priority of the int8 task. Normally lower than or equal to
                  user defined tasks, but may be adjusted to tune responses
                  of TSR's. If there are busy waiting tasks in the system,
                  the priority should be equal to or higher than that of the
                  task that does the busy waiting.
                  The default is PRI_STD.

   AT_BIOS        if TRUE, the AT BIOS wait/post handler is installed.
                  This can normally be left on even for XT type machines.
                  However, some exotic clone BIOS versions have been
                  reported to have problems with INT 15h compatibility, so 
                  for complete portability, this option could be set FALSE.
                  The same effect (although with slightly increased code)
                  can be had by setting the IFL_INT15 flag on installation.
                  The default is TRUE.

      CAUTION:    Changing requires recompile of tskinst.c

   INT8_EARLY     if TRUE, the timer interrupt always uses early INT8
                  processing, regardless of the IFL_INT8_EARLY
                  installation flag.
                  Setting this flag saves some code and data,
                  but eliminates some flexibility. Under DOS, timer
                  ticks can be missed under certain circumstances when
                  set, so DOS based configurations always should use FALSE.
                  The installation flag has a slightly different effect,
                  and may be used under DOS with no adverse effects.
                  Embedded systems likely will always use TRUE.
                  The default is FALSE (use installation flag).

   INT8_LATE      if TRUE, the timer interrupt always uses late INT8
                  processing, regardless of the IFL_INT8_EARLY
                  installation flag.
                  Setting this flag saves some code, but eliminates 
                  some flexibility.
                  Embedded systems likely will always use FALSE.
                  The default is FALSE (use installation flag).

COMMENT ^

   SINGLE_DATA    if TRUE, only a single global data block is used.
                  This speeds up processing, but prohibits linkage
                  of multiple groups. Useful for dedicated systems,
                  and also if your program is known to never interact
                  with another copy of CTask. Should be left FALSE if you're
                  not so sure, must be FALSE if GROUPS is enabled.
                  The default is FALSE.

COMMENT ^

   EMS            If TRUE, EMS support is included. For DOS applications
                  using spawn or going TSR, this should always be TRUE,
                  unless it is known that the program will never be
                  executed in an EMS environment. It must also be TRUE
                  for programs using EMS.
                  The default is TRUE.

   EMS_SAVE_SIZE  Size of the EMS page info save area.
                  For LIM 4.0 drivers, only four pages are saved, 
                  so 16 bytes should be sufficient. If the partial
                  page map function is not available in the driver,
                  more space may be required for holding the full
                  page map.
                  Because some current EMS drivers require more than 
                  the previous default of 16, the default has been raised
                  to 32 for 2.2d.

      CAUTION:    Changing requires recompile of all sources.
