Bar functions

The table below list the bar functions that can be used.

Bit and byte sequence

By default, a bar function defines a bit in a binary sequence. You can switch back and forth to a byte sequence with < and > characters. The < character switches to byte sequence, and the > character switches to bit sequence.

For example

1/1/0/<1/0/>1/0/0/0

Byte translation

Bytes are compiled from the bit/byte sequence in the same order as the bit sequence is entered.

For example:

1/1/1/0/0/0/1/1 = 11100011 = 227

To compile bytes using old INT2OF5 and Code 39 OMR behavior, add a # character in front of the bit sequence. For example:

#1/1/0/1/0/1/0/0/0

Note:

For the old INT2OF5 and Code 39 OMR behavior, this is not recommended when byte sequences are included.

String within the bar function sequence

You can add strings to the bar function sequence by surrounding the string with single quotes. For example

1/1/0/<’25’>/1/0

Barfunction	Description
	Bar is printed.
	Bar is not printed.
seqN	N=1,2,4,8,16,... A bar is printed depending on the binary/byte sequence. See Example 2. Note: In byte representation, this barfunction must be specified as <seq/>. If for example seq=25, the result is the same as 1/<’25’>/1/0=1252
insN	N=1,2,3,4... A bar is printed depending on binary or byte representation of the insert mask. For example, if Insert mask is set to 10, which is 1010 in binary representation, it means that ins2 and ins4 are available to use as inserts for the job. The maximum value of N is 31. Note: In byte representation, the value is a byte instead of a bit.
firstpage	A bar is printed if it is the first page in the document.
notfirstpage	A bar is printed if it is not the first page in the document.
lastpage	A bar is printed if it is the last page in the document.
notlastpage	A bar is printed if it is not the last page in the document.
$variable	A bar is printed depending on value of $variable
$variable[N]	A bar is printed depending on value of $variable and the bit or byte representation. N=1,2,3,4... Bit representation The maximum value of N is 31. For example, if the following bar functions are specified: $page_no[3]/$page_no[2]/$page_no[1] then for $page_no = 3, bars are printed corresponding to 0/1/1. Byte representation N represents the N:th character of the variable. For example: $variable="abcd" => $variable[0]="a", $variable[3]="c" Variable arrays the N:th bit or byte (character) is specified as the second pair square brackets, e.g. $var[0][1], where [1] is the first bit or the second character in the first element of the $variable array.
evenparity	A bar is printed if the number of the other bars is odd. This bar function is used as a security check. If this function is set, the numbers of bars on the sheet must be even. This means that if the number of bars printed to the sheet is odd, the parity bar must be added. If the OMR reads an odd number, there is a misreading. Therefore, security is doubled.
oddparity	A bar is printed if the number of the other bars is even. This bar function is used as a security check. If this function is set, the numbers of bars on the sheet must be odd. This means that if the number of bars printed to the sheet is even, the parity bar must be added. If the OMR will reads an even number, there is a misreading. Therefore, security is doubled.
firstsheetinenvelope	A bar is printed if it is the first sheet in the envelope.
notfirstsheetinenvelope	A bar is printed if it is not the first sheet in the envelope.
lastsheetinenvelope	A bar is printed if it is the last sheet in the envelope.
notlastsheetinenvelope	A bar is printed if it is not the last sheet in the envelope.
Combinations of bar functions
func1&func2	A bar is printed if both func1 and func2 print a bar. Note: The evenparity and oddparity functions cannot be combined.
func1|func2	A bar is printed if func1 or func2 print a bar. Note: The evenparity and oddparity functions cannot be combined.
