MAKDMP creates a dump file for TOPS-20 monitor crashes.

In the filespec you must supply the structure name.  The remainder
of the fields will be defaulted if you do not choose to enter anything.

To indicate the amount of memory you have, use the following information:

Physcial Memory		K Words

.5 megaword		512
1 megaword		1024
1.5 megaword		1536
2 megaword		2048

etc.
