7.2.3. Execution Sequence
If several Formulas were defined, data editing will perform sequentially
from the first Formula to the last Formula. If a Formula is qualified and
executed, the further formulas will be ignored. If none of the Formulas
is executed, the data record will be discarded and there will be no
output to the host.

7.3. Programming
7.3.1. Programming Sequence:
Each Formula is entered into the Reader by the following sequence:
Input_ID
>>
Length
>>
Match
>>
A-String
>>
O-String
>>...>>
O-String
>>
Enter
A Formula starts with Input_ID and ends with “
Enter”
(a label in
programming sheet). If a field is optional and missing, the next one in
the sequence can be entered. But “
Enter”
must be the last input of a
formula.
7.3.2. Preparation
To start the data editing, the following barcode sheets are needed:
-- Programming Sheet.( Setup Sheet in Appendix D).
-- Full ASCII Sheet (Appendix E).
-- Function Code Sheet (Appendix B or C).
