COMAREA

Purpose:    Sets the DOS communication area location.

Syntax:     COMAREA = <STANDARD|HIGH>

By default: COMAREA = HIGH

Note:

     COMAREA = STANDARD instructs the system to use the memory area between
0050:0000  and  0070:000  for its internal purposes.  As the PTS-DOS uses
this memory in not completely the same way as with other DOS versions, some
programs will not operate if COMAREA=STANDARD. When WINDOWS=ON, as it is set
by default, the COMAREA=STANDARD is not executed and it is only permissible
in case if

        WINDOWS=OFF
        COMAREA=STANDARD

     Allocating communication area higher than standard requires 530 bytes
additionaly, which are always in the lower memory area.
