2.56 INTEGER Statement
The INTEGER statement is a type declaration statement and can be used to declare a name to be of type
integer. The implicit type of the name, whether defined by the "first letter rule" (see the chapter entitled
"Names, Data Types and Constants" on page 151) or by an IMPLICIT statement, is either confirmed or
overridden. However, once a name has been declared to be of type integer, it cannot appear in another type
declaration statement.
There are various forms of the INTEGER statement. The following sections describe them.
2.56.1 Standard INTEGER Statement
INTEGER name [,name] ...
where:
name
is a variable name, array name, array declarator, symbolic name of a constant, function name or
dummy procedure name.
This form is the standard form of the INTEGER statement.
Example:
DIMENSION C(-5:5)
INTEGER A, B(10), C
In the previous example, A is defined to be a variable of type integer and B and C are defined to be arrays of
type integer.
2.56.2 Extended INTEGER Statement: Length Specification
INTEGER[*len[,]] name [,name] ...
where:
name
is one of the following forms:
v[*len]
a[*len](d)
a(d)[*len]
v
is a variable name, array name, symbolic name of a constant, function name or dummy
procedure name.
