Variable Character Repeat

The Variable Character Repeat control code may be used to repeat a

count for a character a variable number of times. Any specific ASCII value,

wildcard, or group can be repeated.

The control code requires 4 bytes that give the minimum and maximum

number of times (2 bytes each) that the character may appear in the tem-

plate. Because each OCR line is limited to a maximum of 50 characters,

you can shorten your string by using a variable character repeat. The min-

imum and maximum counts must be in the range from 1 to 50, with the

minimum count less than or equal to the maximum count.

Example: You need to read OCR-B characters that may contain 5, 6, or 7

numeric digits. The string, without repeating variable

characters, would be:

1 2 5 5 5 5 5 1 2 5 5 5 5 5 5 1 2 5 5 5 5 5 5 5 0

Using repeating variable characters, the template would be:

1 2 5 F 0 5 0 7 0
