For those that want to know what the breakdown of the format statement is: the a19 relates to 19 ASCII characters (the string), and the f7.2 relates to a real number set in 7 spaces with 2 decimal points.
Note that the main difference between print and write is that print can never transfer data to user specified output devices, e.g files. Here the answer printed would be: The value of pi is ◊◊◊3.14 (the ◊ represents a blank space). When formatting of output is required, the * can be replaced with a label: real :: pi Fortran Formats Write the format as a character string and use it to replace the second asterisk in READ(,) or WRITE(,). For the character string you can use either single or double quotes. This prints a combination of a character string and a variable. Just as an example, using it from within a do loop: do i1,3 write (, fmt' (1x,a,i0)', advance'no. Multiple write statements with advance'no' can be made at different places in your code in order to print multiple items to the same line. programmathsimplicitnonereal::r,areareal,parameter::pi4.atan(1. The write statement provides an optional advance specifier, but print does not. It is fairly easy to use, for example: print *, 'The value of pi is', pi Basic fortran program Let us write a program to print the area of a circle in your stdout (your terminal). Fortran 77 introduced the print statement, which is more concise. The use of write(*,*) grew out of non-standard use of the write statement in Fortran 66 which was introduced for device-independent sequential I/O.
