ENABLE Reference Manual

ENABLE SCREENS
General Format of the Standard Screen
When you enter a value in the last screen field, the cursor
returns to the first screen field. For applications generated
for T16-652x, T16-653x, and IBM-327x terminals, the cursor does
not automatically tab to the next screen field when positioned in
a key field, the last subentry of a group key field, or the last
field of a nested box.
Multifile applications and applications that access multiple
records use the cursor position to determine which box or record
an operation applies to. When using IBM 327x and T16-651x
terminals, the cursor may be positioned outside of the screen
fields recognized by the application. When this happens, the
application attempts to locate the record to be affected by the
following rules:
1. If the cursor is not positioned in a screen field, the
application assumes that it is located in the next screen
field (down and to the left) of the display.
2. If the cursor is positioned after the last screen field, the
application assumes that it is located in the box and record
image where the previous operation took place.
3. If no operations have yet been performed, the operation
applies to the first record image in the outermost box.
