There is no fixed syntax.
Clarity of expression, rather than rigidity, is the essence of pseudocode.
represent data and identifiers denote higher level functions.
Composed of a sequence
of statements or steps.
Statements are often numbered
Operational (Imperative) statements
include assignment, input, and output.
Control structures provide
and conditional execution. 
Indentations used for
blocks of statements.
- In fact programming systems (and thus algorithms) contain five styles of control: sequencing, condition, iterative, recursive, and abstraction (also known as procedure call). See Lee's law for other examples.
- A variable is a type of object (both is mathematics and programming languages) that can be associated with different values, though in mathematics the value is fixed for the duration of a particular consideration.
- An identifier is a means of "identifying" on object; commonly identifiers are names given to an object. The term "names" commonly infers alphabetic strings. On the other hand, the identifier of a numeric value for example is a numeric string -- such as 3.1415926. "A+B" is the identifer of a particular expression.
