Assignment Statement
Example
The following example defines and references the statement function NETPAY to
calculate the net pay of each employee:
REAL netpay, salary, tax, insure
netpay(salary,tax,insure) = salary-(tax*salary)-insure
DO 5 j = 1,n
READ (*,*) employee, s, t, x

arithmetic-expression
is an arithmetic expression.
character-expression

Considerations
•
Arithmetic assignment statement
When your program executes an assignment statement, FORTRAN evaluates
arithmetic-expression according to the rules described in Section 3,
Expressions. It then converts arithmetic-expression to the type of name, and
stores the value of arithmetic-expression in name. If name is too small to
name =
