How to define a database?
------------------------------------------------------------------------------
(1). Call the Data Master (see chapter 4.1).
(2). Select the Field Editor Menuitem from the Project Menu.
3. Type the number of the fields in the Number of Fields Gadget and
press the <ENTER> key. Now there is the first field of the data-
base on the screen and you can start editing it as below is
advised.
4. Select the type of the field with the Type Gadget. The possible
types are, like earlier, titled 'String', 'Integer', 'Float',
'Type' and 'Boolean'.
5. Enter the field title in the Title Gadget and press <ENTER>
6. Write the field explonation in the Explonation Gadget and press
<ENTER>.
7. If the type is string, set the maximum length of the field data
by using the Text Length Gadget.
8. If the type is integer or float, ...
8.1. Write the minimum and the maximum values in gadgets Min and
Max and confirm with the <ENTER>. If you don't want the
limitation, type 'N' in the gadget. Now on this gadget
appears a text 'No Min' or 'No Max'.
8.2. Type the field unit in the Unit Gadget.
9. If the type is type or boolean, ...
9.1. Set the maximum length of one piece of text with the Text
Length Gadget.
9.2. Determine the number of the alternatives by using the Number
of Alts Gadget if the field type is type.
9.3. Select one of the alternative texts with the Alt.Text No
Gadget.
9.4. Write the respective text in the string gadget at the right
side of the Alt.Text No Gadget and press the <ENTER> key.
9.5. Move to the next alternative text (go back to section 9.3),
until all texts are given.
10. Select the next field with the Field Gadget, and go to section 4.
11. After you have defined all fields correctly (remember to confirm
definitions with the <ENTER> key), select the OK Menuitem from
the Project Menu, and the program returns to the main program.
12. Now the program asks for the estimated number of records, and
then the program allocates memory for these.
13. If there wasn't enough memory, the program returns to the section
12.
14. If there was an old database before calling the Editor, the
program asks if you want to copy the old database to the new
database. If you don't want or if there wasn't any old database,
jump to the section 16.
15. Now you are asked if you want that the program copies the old
database to the new one considering the field titles. If you
answer negatively, this is done so that the data of the old field
number x is copied to the new field number x. Otherwise, the
program copies only those fields that have same titles in both,
old and new, databases.
16. Now the definitions should be ready, and you can start to edit
the records itselves...
