Commands for Building Formulas
The following commands are invoked, followed by the appropriate value entry.
CODE ID | JC<ENTER> |
This command identifies the bar code symbologies or magnetic stripe tracks that will be accepted as valid. Enter the desired Code ID character(s) from the Code ID definition table on page XX after enter- ing JC and <ENTER>. The reader will then limit data input to those symbologies and tracks specified.
SET LENGTH JD<ENTER>n<ENTER>n<ENTER>m<ENTER>m
This command sets the upper and lower limits on the number of characters that will be accepted as valid data. The value of nn (first two digits) sets the minimum length and the value of mm the maximum length. Two digits must be entered for nn and mm so that the reader can correctly parse the command, so if you want the minimum length to be two characters, you must enter a value of “02” for nn. This command is optional.
MATCH STRING
JE<ENTER>n<ENTER>n<ENTER>[STRING TO
MATCH]<ENTER>
This command allows you to “match” any subset of characters (up to a maximum of 60) contained in the scanned input data. The value of nn (first two digits) specifies the position in the input data record that the match is to start. The value of “string” can be any combination of characters (including control and function codes) that can be entered from the ASCII table in Appendix B. Two digits must be entered for nn so that the reader can correctly parse the command, so if you want the match to begin at position 2, you must enter a value of “02” for nn). If you need to match more than one character string, simply add another MATCH command to the formula. This command is optional.
Note: The first position is 01, not 00.
Divide Commands:
These commands are used to divide the data record into separate fields for processing by the data editing program. A DIVIDE command is required in each formula. There are two methods that can be used to divide the record.
1. COUNT | JF<ENTER>n<ENTER>n<ENTER> |
If you enter the COUNT command followed by two numeric digits, you will create one output field, starting at the first position in the input record, that is nn digits long. The dividing pointer will be moved to position nn+1 in the input record. Two digits must be entered for nn so that the reader can correctly parse the command, so if you want to move the dividing pointer two positions to the right, you must enter a value of “02” for nn).
2. SEARCH STRING | JG<ENTER>[CHARACTER STRING] |
If you enter the SEARCH command followed by any character string, the program will search the input data record for a matching string. If a successful match is found, two output fields will be created. The first output field starts at the current position of the dividing pointer and ends at the beginning of the character string. The second field consists of the “matched” string, and the divide pointer is moved to the end of the matched string.
