What is the rule of read data statement?

A successful Format 1 READ statement retrieves a record from the file according to the following rules: The last OPEN, READ, or START verb used for the file determines which record is retrieved. Other file operations do not affect which record is retrieved.

Why are the read and data statement used together?

A READ statement must always be used with a DATA statement. READ statements assign variables to DATA statement values on a one-to-one basis. READ statement variables may be numeric or string, and the values read must agree with the variable types specified. If they do not agree, a "Syntax error" results.

What is the purpose of read statement in Fortran?

The READ statement reads data from a file or the keyboard to items in the list.

How do you read a statement in Fortran?

List-directed input is carried out with the Fortran READ statements. The READ statement can read input values into a set of variables from the keyboard. The first form starts with READ(*,*), followed by a list of variable names, separated by commas.

What is read statement?

The READ statement is used to pick up information for input from external sources. These sources could be input from the keyboard, computer file or a magnetic tape. It can also be used to convert numbers represented within CHARACTER variables to a machine numerical representation (REAL, INTEGER, etc.).

What is a data statement?

With data statement, an author can provide information about the data presented in an article and provide a reason if data is not available to access.

What does the INPUT statement do?

The INPUT statement lets the user type ahead when entering a response. Users familiar with a sequence of prompts can save time by entering data at their own speed, not waiting for all prompts to be displayed. Responses to a sequence of INPUT prompts are accepted in the order in which they are entered.

Is an assignment statement?

In computer programming, an assignment statement sets and/or re-sets the value stored in the storage location(s) denoted by a variable name; in other words, it copies a value into the variable. In most imperative programming languages, the assignment statement (or expression) is a fundamental construct.

What is read variable?

A read/write variable means a variable to which you can assign some value and later on read the same eg var x = 10; writing to it console. log(x) //prints 10 -- reading from it.

What is write statement in Fortran?

The WRITE statement writes data from the list to a file.

What do you mean by formatted and unformatted input output statements in Fortran?

In processing formatted statements, the system interprets some characters, for example, the line-feed character, as special controls and eliminates them from input records. Therefore, unformatted statements must be used when all characters in a record are required.

Is the Fortran language case sensitive?

C and Fortran take opposite perspectives on case sensitivity: C is case sensitive--case matters. Fortran ignores case.

How do you write an if statement in Fortran?

The block IF statement evaluates a logical expression and, if the logical expression is true, it executes a set of statements called the IF block. If the logical expression is false, control transfers to the next ELSE , ELSE IF , or END IF statement at the same IF -level.

What is free format in Fortran?

In Fortran 95 the code layout is obeys the following rules, which describe the ``free source form''. statements can begin in any column; multiple statements on a line are allowed; they have to be separated by semicolon ``;'' an exclamation mark ``!
