A Simple Example
The example shows data being entered into version4.1 of the software.
Since it is almost impossible to predict the types of material you are likely to recover on your particular projects, we will invent a fictitious example for the purposes of showing you the process of using ProLog.
Before you think of complaining that there is not enough data to represent real life, the intention of this example is purely to demonstrate the process you need to use to get the data in, and the graphic and english logs out the other end.
Once you are familiar with the process you can fill in as much detail as you think is warranted.
The following Table contains details of the material recovered from Borehole 1234 on Project Anyhole.
Coal Weathered
Coal - Dull Banded
Coal Dull
Coal Dull & Bright
Coal Dull & Bright
For the purposes of the exercise we have dispensed with many of the colours or other items you will strike in real life, but there is enough here to get a picture at the end of the process.
The first step in the process is to ensure that all of the most common Lithologies, colours, etc you intend to use are entered in the relevant table as described above.
Here you should look through the data table above and check the materials against the default table supplied.
For this example you should see that all the items are in the table.
However in real life, it is unlikely that you will be so fortunate, so now is the time to sit down with a pad and pencil and list down all the entries you are likely to use, and the unique codes you wish to use to signify each entry.
Then edit the table to suit, bearing in mind that if you miss a particular entry, you can always type it in manually.
Next, you should check that there is a hatch pattern available for each of the materials you have recovered.
To do this, you need to use Wordpad or NotePad or similar to open the file called ‘hatch’. This can be done from the “Setup” menu – “Edit/View hatch in Notepad”.
Look through each of the names and check off to make sure each of your intended entries is available.
Again, fortune will have smiled on you for the purposes of this example, but in real life now is the time to look through the chapter titled hatching (or the topic in the on line manual) to determine how you will define the pattern you need for materials not already in the file.
You can also copy and paste an existing hatch entry and change the heading. This is useful if an existing entry gives you the same output as the one you want.
Once all is in readiness you should Start ProLog.
Pull down the File Menu and select New.
The program will offer to open a new file in the data folder. This is found under my documents/prolog4. You may accept this or create your own folder.
Use the icon of the folder with an arrow to go up one level, then select the folder named ‘examples’ displayed.
In the field titled ‘File Name’ type in "borehole1234.prolog" and then select Open. We recommend that you include the .prolog extension so that you know this is a prolog file.
The program will inform you that the file does not exist and ask for confirmation that it should be created so please humour it and select the Yes option.
You will now be presented with the following screen, or at least one similar to it, depending on how closely you followed earlier instructions for configuring prompts.
You may need to change the template used. ie the headings, pop up box's etc. From "File" menu click on the "read template". There are some default templates supplied with Prolog. Select the traditional template. If you select the Spanish version - you have Spanish entries.
The cursor will be flashing in the field titled “Lithology”.
The entry you need is Soil, which you can enter by either typing in the code of ‘SO’ followed by Enter, or by using your mouse to select it from the table.
You may then enter colours or other items as the mood takes you, but the important thing is to position the cursor in the field titled Recovered.
Type in 1 then press Enter.
Press Enter twice more to accept the value of 1 being placed in Est Thickness and Est Depth.
The cursor will now appear back in the Lithology field redy for the next entry which is Clay.
Either pick with the mouse from the table, or type in CL followed by Enter.
Enter a value of 4.8 for recovered and press Enter until the cursor return to the Lithology field.
Now Enter 1 metre of Claystone followed by 4.7 metres of Sandstone.
Once you have finished the Sandstone entry, you will be prompted for another lithology, but before you press on, lets have a look at progress to date.
If you are using a sufficiently large screen and screen resolution, you may see the small column titled “Graphics” as you progress.
If, however you are using the typical Notebook at around 800x600 this will be obscured by the Lithology Table.
If you move the cursor to the Colour Field, you will see a blanked out Graphic.
Select the Icon showing the arrow pointing upwards to indicate you wish to view the previous entry.
The screen will now appear as below.
If, as we have suggested, you have restricted the number of entry fields on display, you might like to drag the “graphic” window down to the vacant area at the lower left of screen as below.
Enough of the pretty pictures; and back to the grind.
You need to work your way through the table adding in each of the entries until you have finished.
If you wish, you may then use the Icons with the arrows pointing up and down to move up an down through your entries.
You will see on the “Graphic” window that the current entry is outlined in red to indicate where you are.
We would also point out that while this example only has 14 entries, you should get into the habit of Saving periodically as you work.
You can decide for yourself how much you are prepared to lose if the power goes out, but probably a Save after every 15 or 20 entries is probably a good insurance policy.
