1.9 Assignment StatementsA Fortran assignment statement can be any of the following:• An intrinsic assignment statement• A statement label assignment• An array assignment• A masked array assignment• A pointer assignment• A defined assignment1.9.1 Arithmetic AssignmentThe arithmetic assignment statement has the following form:object = arithmetic-expressionwhere object is one of the following:• Variable• Function name (within a function body)• Subroutine argument• Array element• Field of a structureThe type of object determines the type of the assignment (INTEGER, REAL, DOUBLEPRECISION or COMPLEX) and the arithmetic-expression is coerced into the correct type ifnecessary.In the case of:complex = real expressionthe implication is that the real part of the complex number becomes the result of the expressionand the imaginary part becomes zero. The same applies if the expression is double precision,except that the expression will be coerced to real.The following are examples of arithmetic assignment statements.26 Chapter 1
A=(P+Q)*(T/V)B=R**T**21.9.2 Logical Assignment StatementThe logical assignment statement has the following form:object = logical-expressionwhere object is one of the following:• Variable• Function name (only within the body of the function)• Subroutine argument• Array element• A field of a structureThe type of object must be logical.In the following example, FLAG takes the logical value .TRUE. if P+Q is greater than R; otherwiseFLAG has the logical value .FALSE.FLAG=(P+Q) .GT. R1.9.3 Character AssignmentThe form of a character assignment is:object = character expressionwhere object is one of the following:• Variable• Function name (only within the body of the function)• Subroutine argument• Array element• Character substring• A field of a structureAbove, object must be of type character.None of the character positions being defined in object can be referenced in the characterexpression and only such characters as are necessary for the assignment to object need to beLanguage Overview 27
