    variable that causes VER to report that it is DR-DOS version 6 but 
    MANIFEST reports its response to the DOS API call that identifies 
    the version for API purposes.  For all programming purposes, DR-DOS 
    6 is version 3.31.  There is no SETVER command, nor is it 
    necessary.
        2)  DR-DOS converts FCBS to FILE handles so MANIFEST and 
    FILES.COM will report the total number of FILE handles to be the sum 
    of the two.  The minimum number of FILE handles is 20 and the 
    minimum number of FCBS is 4.  This conflation of FCBS and 
    FILE handles causes Manifest to report that there is only one
    FCB.  MANIFEST reports that there is only one FCBS but it is 
    mistaken. 

DESQVIEW

        1)  The HISTORY feature does not work inside DESQview.  There 
    is no work-around.
        2)  DR-DOS allows the kernel and buffers to be loaded into UMBs. 
    It also allows them to be loaded into the HMA.  DESQview uses the 
    entire HMA while DR-DOS cannot.  (DR-DOS's kernel uses 37K, and 
    HIBUFFERS can fit only 35 buffers into the HMA along with the 
    kernel.  Each buffer uses .5K when loaded into a UMB or low, so DR-
    DOS can use only 54.5K of the HMA, 9.5K less than DESQview.)  Since 
    the HMA cannot be shared, any unused portion is wasted.  DESQview 
    users will have more memory available if DESQview uses the HMA 
    rather than DR-DOS.

        3)  The task switcher, TaskMAX, will not run in DESQview.  
    There is no work-around.
        4)  There is no SETVER command, nor is it necessary, as 
    explained in the MANIFEST section of this technote.
