Either way, it is possible to define them all in one go (possibly as a list-defined reference) and invoke them several times (possibly with different |page= parameters, or to define the citations individually and combine them through the annotation system of template {}. The following examples illustrate the latter form:
A variable-length record is a record in which the size of the record in bytes is approximately equal to the sum of the sizes of its fields. This was not possible to do before more advanced storage hardware was invented because all of the punchcards had to conform to pre-determined document lengths that the computer could read, since at the time ...
Compile: The DBMS compiles (parses, optimizes and translates) the statement template, and stores the result without executing it. Execute: The application supplies (or binds) values for the parameters of the statement template, and the DBMS executes the statement (possibly returning a result). The application may request the DBMS to execute the ...
The term template, when used in the context of word processing software, refers to a sample document that has already some details in place; those can (that is added/completed, removed or changed, differently from a fill-in-the-blank of the approach as in a form) either by hand or through an automated iterative process, such as with a software assistant.

[13] This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasirelational database management system, System R, which a group at IBM San ...
