The data-entry keyboard functions in either numeric shift (upper) or alphabetic shift (lower).
The upper symbol (for the keys with two symbols) is typed when the keyboard is in uppershift. On this keyboard, the numbers 0 through 9 are the upper symbols on alphabetic keys. The lower symbol (for the keys with two symbols) is typed when the keyboard is in lowershift. The alphabetic characters A through Z are the lower symbols and are always in uppercase. The data-entry keyboard does not support lowercase characters a through z, even if you specify CHECK(LC) keyword.
The following figure shows the data-entry keyboard.
Note that you type the numbers 0 through 9 by using the lowershift on the typewriter-like keyboard and by using the uppershift (numeric) on the data-entry keyboard. Therefore, when a field has one of the numeric keyboard shift attributes (numeric shift or numeric only), the typewriter-like keyboard is in lowershift and the data-entry keyboard is in uppershift. In both cases, you can type numeric characters without pressing a shift key.
