Performs a bit-wise AND of two values.
|char1||a character string, or an expression that evaluates to a character string|
|char2||a character string, or an expression that evaluates to a character string|
The $and function combines the bit patterns of two characters in the fashion of a Boolean AND and returns the resulting character. If the char1 or char2 string contains more than one character, only the first character in the string (one byte) is processed. You can express char1 and char2 as hex codes (e.g., 6E).
