Geometric Calculations.
GEO© module serves for Geometric Computations (COGO). 
The most practice innovation in GEO© is the usage of automated scripts which activates in OnLine Real-Time mode. 
This method is very useful for cadastre calculations and subdivision. 
GEO© calculates the script commands in sequential order so the user can immediately see the influence of one step on all its previous commands. 
Three basic windows in GEO©: 

List of Commands.
Old registration field books usually contains borders measurements in chain surveying techniques. For reestablishing the old boundaries we must reconstruct the original process.
GEO© commands help us to simplify and clarify the bulk of calculations and saves us a lot of time in case of errors in the original data or in case of changing element's values.
The process of creating GEO© script is very easy: We just have to select the desired command from the INSERT window, then to fill in the measurements and that's all !!, go to the next command and so on. Meanwhile GEO© will calculate the results (Points Coordinates or Computation Variables) and report them in an appropriate form.

Example of the RunOffset Command Form.
This example shows the command which calculates the right angle projection of a point over a measurement's line. Here the reference line defined from point "SE" to "NW" and the point being imposed is "1" (their coordinates declared before).
Immediately after pressing  it will be calculated and the results will be stored in the variable tables (storage ^3 and ^4 respectively). In this case the run distance is 212.14 meters and the offset length is -56.57 meters (minus sign for the left side).

Scrip Form (Main).
The Main form shows the sequential order of all the script commands and their status. A command status can be: =Executed OK; =Executed with some warnings; =Not calculated yet; =Error occurrence-not executed. We also have the ooption to enable/disable commands or to lock/unlock them.

Results Form (Points).
The Results form contains 8 pages. In each of them it's corresponding calculation's results. The Points page affected by the POINT command or by any other command which loads or creates points coordinates.

Results Form (Variables).
The Variables page show the current values stored in the program stack. For example if we'll look at command #15 in the script form we'll see this .
It compute the Azimuth and the Distance from the station point name "O" to the target point "2" and store results at stack locations ^1 and ^2 respectively. We can see below that the Azimuth is  and the distance is 90.55 meters.
