CT was modified to handle more than 64K QSOs for the ZA1A logs, so that
should not be the problem.

Since like me you are running OS/2 Warp at home, just set up a VDM
(Virtual DOS Machine) with 6 meg of DPMI memory, 0 meg XMS and 0
meg EMS.  Then, fire up CT in that VDM in DXpedition mode with -d for the
super-check partial database, and type MEMLEFT.  That will tell you
how many QSOs CT thinks it can store on a machine with 6 meg of

After exiting CT type MEM at the DOS prompt to see how much conventional
memory OS/2 is giving the VDM.  This number may be larger than the amount
of conventional memory a machine running native DOS will have, so you should
adjust the MEMLEFT number down somewhat to get a more accurate estimate.
