In CL environments of the Pascal variety there are several different ways that higher order signs are created.  In these settings higher order signs, or signs for referring to signs as objects, can be implemented as the ''codes'' that serve as numerical identifiers of characters or the ''pointers'' that serve as accessory indices of symbolic expressions.

But not all the signs that are needed for referring to other signs can be constructed by means of quotation.  Other forms of higher order signs have to be generated ''de novo'', that is, constructed independently of previous successions and introduced directly into their appropriate orders.  Among other things, this obviates the usual strategy for telling the order of a sign by counting its quota of quotation marks.  Failing the chances of exploiting such a measure in absolute terms, and in the absence of a natural order for the construction of signs, the relative orders of signs can be assessed only by examining the complex network of denotative and connotative relationships that connect them, or the gaps that arise when they fail to do so.

In a CL context this often occurs when a constant is declared equal or a variable is set equal to a quoted character, as in the following sequence of Pascal expressions:

In a CL context this often occurs when a constant is declared equal or a variable is set equal to a quoted character, as in the following sequence of Pascal expressions:

const comma = ',' ;

| <code>const comma = ',' ;</code>

In this passage, the sign &ldquo;<code>comma</code>&rdquo; is made to denote whatever it is that sign &ldquo;<code>','</code>&rdquo; denotes, and the variable <math>x\!</math> is then set equal to this value.

 

In this passage, the sign <comma> is made to denote whatever it is that sign <','> denotes, and the variable x is then set equal to this value.
