ENABLE Reference Manual

ENABLE SCREENS
General Format of the Standard Screen
Line 2 also displays a message when the application has
performed a successful read operation. The message indicates
the type of read operation performed and the name of the key
field that was used. You can use this information to
determine how the application will process a READ NEXT
operation.
• Lines 3 through 20 display screen label and field pairs.
• Line 23 displays a message whenever the application
successfully completes an operation.
• Line 24 displays a message if an error occurs during
application execution. The message is highlighted and
persists until you press an ENABLE function key.
If this line displays a message immediately after the
application executes but before any action can begin, an error
that prevents the application from performing any operations
has occurred. If this message appears, the application
terminates as soon as you press any ENABLE function key.
For T16-652x and T16-653x terminals, a message displayed on
line 24 appears in DIM REVERSE video. For T16-651x
terminals, a message on line 24 appears blinking.
Appendix C lists the messages that might appear on this line.
Screen Label and Field Format
The following rules apply to the format of the label and field
pairs displayed on a standard screen:
• Field names from a record description appear as labels.
• Fields declared as FILLER in a record description remain in
the record but they do not appear on the screen and,
therefore, you cannot update them. The application gives
these fields null values if you perform an insert operation.
• Bracketed subscripts appear with the labels of fields declared
with an OCCURS clause in a record description; for example:
COMMENT[1] _____________________________
COMMENT[2] _____________________________
