1.Use memo fields for text strings that are too long to store in an alpha field.
Memo fields can be virtually any length. The size value you assign refers to the amount of the memo Paradox stores in the table. This can be from 1 to 240 characters. Paradox stores the whole memo outside the table (in the .MB file). Paradox retrieves the data from the .MB file as you scroll through the records of the table. The amount of data a memo field contains is limited only by the disk space available on your system.
Tip: If all your memos are smaller than a given size (for example, 200 characters), you can save space and time by setting the memo field size to be equal to or larger than this given size. You will still have an .MB file, but Paradox will not have to access it to display the field's data.
Memo fields can contain letters, numbers, special symbols (such as %, &, #, and =), or any other printable ASCII character (except null). You can enter line breaks, tabs and other print control characters in memo fields.
Controlling the display of memo data
In viewing a table with memo fields, you can use the Complete Display setting of the Run Time property to control the display of memo data. First, display the Text properties: Press Shift+F2 to enter Memo View, then right-click, choose Properties, and choose the Run Time page tab. Then,
Check Complete Display if you want to see all the record values displayed all the time.
Uncheck Complete Display if you want to see only the value of the current field. Tip: This lets you move through the records of the table more quickly.

А что в 2004 году кто то еще серьёзно использует Paradox ?
Ты, наверно, будешь удивлён, но и в 2004 году есть некоторый круг задач, для которых Paradox подходит лучше, чем Interbase или Oracle.
