Chapter 1 - About 3270 and 5250 Programming The next table lists computer-supported FCWs and functions: Supported FCWs and Functions Value (Hex) Description 80nn 8101 8103 84nn Entry field resequencing. The "nn" specifies the next entry field in the sequence (hex 00 to 80). Magnetic stripe reader (MSR) entry field. MSR and selector light pen (SLP) entry field. Transparency entry field. The "nn" is any two digits. B140 B1A0 Self-check modulus 11 entry field. Self-check module 10 entry field. The first FCW of any type is used and subsequent FCWs of the same type are ignored. The controller does not check to see if the FCWs are formatted correctly or if the requested function is installed. During subsequent command and keystroke processing, the controller detects and reports these errors to the host if the FCW is required. FCW types are as follows: • Entry field resequencing. This enables the controller to send the input fields to the host in any specified order. Resequencing is done by chaining input fields with FCWs that specify the desired order of transmission. The resequencing FCW takes the following format: Bits Description 0-1 B 10 2-7 B 000000 8-15 The normal sequence position of the next field to be returned to the host. The first field on the screen is number 1. Field numbers progress sequentially, left to right and top to bottom. Bit 3 of the SOH order contains the number of the field to be sent. If the first field identifier in the SOH is zero, resequencing does not occur. That is, all resequencing FCWs are ignored. Fields are sent to the host in the order defined in the format table. If resequencing occurs, the last field to be sent to the host must contain this FCW: Bits Description 0-1 B 10 2-7 B 000000 8-15 B111111111 Note: If FCWs create a closed loop, the controller detects the error and stops the transmission. An FCW for each field is not required, but one pointing to the next sequential field is assumed if no resequencing FCW is specified. The last field in the table must have a resequencing FCW.

The next table lists computer-supported FCWs and functions:
The first FCW of any type is used and subsequent FCWs of the same type are
ignored. The controller does not check to see if the FCWs are formatted correctly or
if the requested function is installed. During subsequent command and keystroke
processing, the controller detects and reports these errors to the host if the FCW is
required.
FCW types are as follows:
•
Entry field resequencing. This enables the controller to send the input fields to
the host in any specified order. Resequencing is done by chaining input fields
with FCWs that specify the desired order of transmission. The resequencing
FCW takes the following format:
Bit 3 of the SOH order contains the number of the field to be sent. If the first
field identifier in the SOH is zero, resequencing does not occur. That is, all
resequencing FCWs are ignored. Fields are sent to the host in the order defined
in the format table. If resequencing occurs, the last field to be sent to the host
must contain this FCW:
Supported FCWs and Functions
Value (Hex)
Description
80nn
Entry field resequencing. The “nn” specifies the next entry field in the
sequence (hex 00 to 80).
8101
Magnetic stripe reader (MSR) entry field.
8103
MSR and selector light pen (SLP) entry field.
84nn
Transparency entry field. The “nn” is any two digits.
B140
Self-check modulus 11 entry field.
B1A0
Self-check module 10 entry field.
Bits
Description
0-1
B 10
2-7
B 000000
8-15
The normal sequence position of the next field to be returned to the host. The
first field on the screen is number 1. Field numbers progress sequentially, left
to right and top to bottom.

Note:
If FCWs create a closed loop, the controller detects the error and stops the
transmission. An FCW for each field is not required, but one pointing to the
next sequential field is assumed if no resequencing FCW is specified. The last
field in the table must have a resequencing FCW.
