The following are all statements:
Name | Description |
---|---|
AUTOMATIC | Declares a variable on the stack, rather than at a static memory location. |
BYTE | Specifies variables as the BYTE data type; BYTE is equivalent to INTEGER(1). |
CHARACTER | Specifies variables as the CHARACTER data type. |
COMPLEX | Specifies variables as the COMPLEX data type. |
DATA | Assigns initial values to variables. |
DIMENSION | Identifies a variable as an array and specifies the number of elements. |
DOUBLE COMPLEX | Specifies variables as the DOUBLE COMPLEX data type, equivalent to COMPLEX(8). |
DOUBLE PRECISION | Specifies variables as the DOUBLE-PRECISION real data type, equivalent to REAL(8). |
EQUIVALENCE | Specifies that two or more variables or arrays share the same memory location. |
IMPLICIT | Specifies the default typing for real and integer variables and functions. |
INTEGER | Specifies variables as the INTEGER data type. |
LOGICAL | Specifies variables as the LOGICAL data type. |
MAP | Within a UNION statement, delimits a group of variable type declarations that are to be ordered contiguously within memory. |
NAMELIST | Declares a group name for a set of variables to be read or written in a single statement. |
PARAMETER | Equates a constant expression with a name. |
PROTECTED | Specifies limitations on the use of module entities. |
REAL | Specifies variables as the REAL data type. |
RECORD | Declares one or more variables of a user-defined structure type. |
SAVE | Causes variables to retain their values between invocations of the procedure in which they are defined. |
STATIC | Declares a variable is in a static memory location, rather than on the stack. |
STRUCTURE | Defines a new variable type, composed of a collection of other variable types. |
TYPE | Defines a new variable type, composed of a collection of other variable types. |
UNION | Within a structure, causes two or more maps to occupy the same memory locations. |
VOLATILE | Specifies that the value of an object is totally unpredictable based on information available to the current program unit. |
