Field Type Description
Alpha only Accepts only th e ch aracters A-Z (uppercase and lowercase) and the , . - and blank space.
Alpha shift Acceptsalldatakeys.Theshiftkeysareacknowledged.
Auto enter When the operator uses [FIELD EXIT] key to leave th is field or puts the last characte r in
the field, the terminal treats the action as if the operator pressed [ENTER].
Bypass Operator cannot put entries in this field. Attempts to ente r data cause a keying e rror.
Digits only Operator can only put the characters 0-9 in this field. The [DUP] key is allowed if enabled.
Duplication Allows operator to use the [DUP] key. When the operator presses [DUP], the controller
fills the field from the cursor to the end of the field with “1C.” (Typically the host program
uses th is to place data from a previous record into the field when it receives the data.) An
overstruck asterisk is displayed for the “1C” characters.
Field Exit key required Operator can only exit the field by pressing a non-data key such as [FIELD EXIT] or other
cursor-moving key.
I/O Only th e s canner can put data i n this field.
Mandatory entry The operator must put data in this field before pressing [ENTER] or another
AID-generating key.
Mandatory fill Whe n the operator begins putting data into this field, the y must completely fill it before
exiting from it.
Modified Marksthisfieldasmodified.
Numeric only Accepts only the characters 0-9 and the symbols + , . - and blank. [FIELD+] exits th e field
with a positive number; [FIELD -] with a neg ative number. [FIELD EXIT] e xits the field
as entered with the sign specified by the host. The controller marks a minus field by
changing the hig h nibble of the last byte to “B” unles s a + , . - or blank is in that byte.
Thes e ch aracters cause an error to occur.
Numeric shi ft Accepts any data characters .
Right-adjust When the operator exits the field, the controller shifts th e contents to the right and fills on
the left with zeros or blank spaces, as specified. Bits 13-15 can be 0. This allows the
operator to make entries into any part of the field without any subseq uent position
adjustment. When the controller sends the field to the host, it also sends whatever is in the
field (nulls if a Clear Unit command was received).
Self-check Modulus 10 self-check fields perform a MOD 10 Check on the input. Modulus 11
self-check fields perform a MOD 11 Check on the input. The controller performs these
checks when the operator exits the field. If the checks fail, an input error is indicated and
the Input Inhibited a nnunciator is t urned on. Th e operator must press the [RESET] key to
clear the condition.
The network checks data by doing the appropriate modus on the low four bits of the
characters in th e field. If th e low four bits are within the range “A” through “F,” zero is
used in the modulus calculation.
Signed numeric Only the characters 0-9 are allowed. The last byte of the field is re served for the sign
character. The operator cannot place data in this location. If the operator presses [FIELD-]
to exit the field, the last character is set to “ -” and the field is right adjuste d. The high
nibble of the last digit input is set to “B.” If the operator uses [FIELD+] or [FIELD EXIT]
to exit the field, the last character is set to blank and the field is right-adjusted. The “-” or
“blank” is s ent in response to Read Input Fields or Read MDT Fields commands.
