S-expression
Atom
List
Predicate
In LISP programming if X and Y are S-expressions then the dotted pair (X.Y) is also considered as S-expression.
What are the basic building blocks of S-expressions?
Atoms
Lists
Numbers
Predicates

What is the use of (WRITE 'Argument)?
It converts argument in small letters to capital letters
It returns capital letters from the string

Atom
Error will occur
S-expression
Primitive
According to recursive definition of S-expression if S1, S2, S3... are S-expressions then list: (S1 S2 S3 ....) is also an S-expression. S-expression is short form of symbolic expressions.
