Decl values and headings both accept decimal numbers.

Subject: [DMU] pushing the limits
I am still attempting to construct a map of the first generation of
settlers in a 100 square mile area in Weakley Co TN. I have about 600 deeds
plotted and about half of them linked or connected together. I am beginning
to push the limits of my computer's ability to handle all the data. Things
were OK until I finally figured out how to correct the original survey grid
to accurately portray these plots on a modern map. I have several
1. When I put in an "include" statement, my computer slows
down a great
deal. I have 128MB RAM on a 750 MHz processor. I see the slow down
scrolling. If I scroll too fast the machine freezes or crashes. Is this
2. I am running Deedmapper 3.0 build 7. It appears to accept a decl
value that is a decimal (like 1.5 degrees) Later on I was crashing. Can
decl be a decimal value or must it be an integer.
3. same as two for compass bearings. Is "N9.5E;;" an
or must I use integers?
4. I have used lots of labels or annotations on my plots. Do these
lots of memory and could this be a significant contributor to my slow down.
5. I am using a small fractikon of the background map. I am
the seam of four topos I purchased from you. Could this be significant?
Should I try to cut the map down to the area I am using? If so, how do I do
Thanks for the assist. As you can see I am heavily committed to your
product and use it extensively. I just want it to do more.
