Bit-string literal

Manipulating arrays, assigning values to arrays and forms of expression for array (bit-string) literals are discussed in Chapter 5. 

Bit-string literals are a common form of expression for BIT VECTOR assignments. Wa) of expressing these literals are discussed in Chapter 5,... 

The examples so far have illustrated the use of only standard integer literals such as 0, 10 and 255. However, like bit-string literals, numeric literals can be expressed in several forms. In a s)mfhesis environment the use of numeric literals is limited to the integer and based types. Examples of the forms that integer literals may take are as follows. 

Assuming that - operator functions are defined for both array types and are located in a visible library, how does the synthesizer know whettier these bit-string literals represent BIT VECTORs or SIGNED binary numbers The designer must therefore qualify the type of each literal, namely ... 

String literals can generally only be used in synthesis if each character of the string represents a discrete enumeration literal and hence a single bit encoded value. Hence, an array of type BCX)LEAN could be formed using aggregates but not strings as illustrated below.
