This is the correct answer.  Unfortunately, I have my doubts as to whether
most MS-DOS Icon implementations can support HEAPSIZE values larger than
64K due to the segmentation of the 8086 architecture.  Large Icon programs
have to be designed well in order to run under MS-DOS.  Version 8.0 of
Icon is more space-efficient in its use of the block region.
