Chapter 1 - About 3270 and 5250 Programming Field Types (continued) Field Type Description 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 this 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 Operator can only exit the field by pressing a non-data key such as [FIELD required EXIT] or other cursor-moving key. I/O Only the scanner can put data in this field. Mandatory entry The operator must put data in this field before pressing [ENTER] or other AID-generating key. Mandatory fill When the operator puts data into this field, they must completely fill it before exiting. Modified Marks this field as modified. Monocase Keyboard enters only uppercase characters A to Z in the field, regardless of the Shift state. Numeric only Accepts only the characters 0-9 and the symbols + , . - and blank. [FIELD+] exits the field with a positive number; [FIELD-] with a negative number. [FIELD EXIT] exits the field as entered with the sign specified by the host. The controller marks a minus field by changing the high nibble of the last byte to "B" unless a + , . - or blank is in that byte. These characters cause an error to occur. Numeric shift Accepts any data characters. Right-adjust When the operator exits the field, the controller shifts the contents to the right and fills on the left with zeros or blank spaces, as specified. Bits 1315 can be 0. The operator can make entries into any part of the field without any subsequent 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). Signed numeric Only the characters 0-9 are allowed. The last byte of the field is reserved 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 adjusted. 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 sent in response to Read Input Fields or Read MDT Fields commands. About Field Control Words Field control words (FCWs, two bytes each) are optional. The user program can use the Write to Display (WTD) command to send FCWs to the controller. When FCWs are used, they should follow the FFW of the SF order. FCWs found during modification of existing format table entries are ignored. LU does not accept an FCS of hex FFxx. 34 Intermec Terminal Emulator (ITE) Programmer's Reference Manual
