 = ASCII numbers that define the code length where: 
•  First 2 digits = minimum acceptable code length. 
•  Second 2 digits = maximum acceptable code length. 
The minimum code length must always be less than or equal to the maximum. The maximum 
code lengths are 99 characters. 
Examples: 
0132 = variable length from 1 to 32 digits in the code. 
1010 = 10 digit code length only.
