If you have been having problems with the DTB, DTF, or DT function
on the Applied Microsystems Development system, I may have a cure for
you.  Apparently, the Devsys has quite a few bugs still, one of which
is that the DTx function will lock up the system if there are too many
symbols.  A temporary cure for this is to selectively delete symbols
from the file that you download.  I have changed Jim Morris' gensym
program to allow an optional third file.  To use the new gensym program:

    In you login.com:
	csym :== $sys$userdisk:[packrat.68000]gensym

    In your link68.com:
	$ csym file.ab file.sym [file.exc or file.inc]

    What this .EXC or .INC file will do, is look for symbols that match
the strings in the file.  If there is a match, then the symbol is
either left in the .SYM file if the extension is .INC, or left out of
the .SYM file if the extension is .EXC.  Some examples:

	ab*
	M_FOO
	M_G*

    will match any string starting with ab, a string called M_FOO, and
any string starting with M_G.  Any letters after the * will be ignored.


    So, a recap, if you want to exclude a set of symbols, use a file called
file.EXC, and fill the file with strings to match the symbols you don't
want.  If you want to keep a specific set of symbols, then use a file
called FILE.INC, and fill the file with strings to match the symbols you
want to keep.
