Internal Image is the internal representation that OCR stores for this character. Internal Image is an 8-bit image.

IMAQ OCR Session specifies the OCR session on which this VI operates. To create a session, use the IMAQ OCR Create Session VI.

Character Image is the image you used to train this character. Character Image can be of type 8 bit, RGB, or HSL.

error in (no error) describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

	status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

Character Index is the index of a character in the character set.

Internal Image (out) is valid only if you specified an Internal Image. Internal Image returns the internal representation that OCR stores for this character.

IMAQ OCR Session (dup) is the reference to the OCR session to which this VI operates.

Character Image (out) is valid only if you specified a Character Image. Character Image (out) returns the image that OCR used to train this character.

Character Value is the value of the corresponding character.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

Is Reference Character is TRUE if the character is the reference character for the character class.
