S If the master MDT bit is on, the user receives:
Cursor Address AID Code Field Data
S Cursor Address:
Position of the cursor when the AID-generating key was pressed.
S AID Code:
Code for the AID-generating key the operator used.
S Field Data:
Returned only when one of the following AID-generating keys is
used:
S Roll Up
S Roll Down
S Enter/Rec Adv
S An unmasked function key
When it is returned, the field data consists of the contents of all input
fields as they appear on the display unless resequencing was specified.
Any attributes in a field are treated as data and returned as such. Field
attributes are not considered part of the f ield. All nulls are converted to
blanks. All pending AID r equ est bytes are cleared. If the specified field is
signed numeric, the first character is not sent; if that same field is negative,
the zone position of the next-to-the-last character is changed to hex D.
Though data is not sent, the CC bytes are processed.
To determine the appropriate codes for the control character (CC) bytes,
see the “Write T o Display” topic (page 278).
Format
The format of the returned data is:
Bytes 1 and 2 Byte 3 Byte 4 Byte 5
Cursor address AID code Field data Field data
Byte 6 and all that follow contain the remaining field data from the format
table. The terminal returns complete contents of each field, with nulls con-
verted to blanks.
