1. A method for changing a function of a bar code reader, which is capable of reading data code symbols, by reading of a bar code reader function symbol, comprising the following steps:
- scanning a bar code symbol;
determining whether or not the scanned bar code symbol has been properly sensed;
determining whether a properly sensed bar code symbol possesses a certain characteristic which identifies it as not being a data code symbol;
determining whether a sensed bar code symbol which is not a data code symbol is a bar code reader function symbol;
identifying the specific reader function encoded in a sensed bar code reader function symbol; and
performing the encoded function.

Abstract
A bar code reader is provided with the capability of reading bar code symbols containing information for causing changes in the functions performed by said reader, as well as reading merchandise identification symbols commonly associated with items such as merchandise being checked out at a point of sale terminal. Tests are provided to determine that the bar code symbols for function changes are proper symbols, and are not merchandise identification symbols, such as UPC symbols.
