![]() ![]() This is used for real output in exponential notation. If the field width is not large enough to accommodate the real number then the field is filled with asterisks. Real values are right justified in their fields. This takes the form ‘rFw.d’ where the meanings of r, w and d are given in the table below. If the field width is not large enough to accommodate an integer then the field is filled with asterisks. Integer values are right justified in their fields. This takes the form ‘rIw.m’ where the meanings of r, w and m are given in the table below. The following table describes the descriptors − Descriptor It consists of a string, containing a list of edit descriptors in parentheses.Īn edit descriptor specifies the exact format, for example, width, digits after decimal point etc., in which characters and numbers are displayed. Variable-list is a list of the variables to be read from keyboard or written on screenįormat specification defines the way in which formatted data is displayed. Formatted Input Outputįormatted input output has the syntax as follows − ![]() However the formatted I/O gives you more flexibility over data transfer. #Blank line simply fortran free#The free format simple I/O has the form − This form of input-output is free format I/O, and it is called list-directed input-output. You can configure the number of spaces to use also.We have so far seen that we can read data from keyboard using the read * statement, and display output to the screen using the print* statement, respectively. ![]() $ lfortran fmt -indent-unit tests/subroutine4.f90 Now, for LFortran we made this configurable: $ lfortran fmt tests/subroutine4.f90 You can also change from 4 spaces to 3 or 2 spaces. #Blank line simply fortran code#But I don’t like doing that, I rather start all executable code at column 1. A typical solution is to give up fitting into 80 columns. If you increase it to 3 loops which is common, you will run out of space. The example you posted runs over 80 columns with one comment due to that. I also like to stick to 80 columns, because then I can have multiple terminals open side by side. I do like using 4 spaces and then you very quickly run out of horizontal space. The stdlib example you posted wastes 8 spaces for any executable code. That said, if you are contributing to a project such as stdlib, you should follow the style of that if possible, let’s allow people to choose the indentation they like and respect that.įor example, I agree 100% with and follow the same conventions. Text = text.replace("real(dp)","real(kind=dp)") # reformat some declarations Here is a Python script to undo some indentation: # remove the the first nleading spaces from lines of infile It would be wasteful and tedious to indent every line in a paragraph except the first. In English, you may indent the first line of a paragraph or not indent but have blank lines between paragraphs, as in this message. Avoiding unnecessary indentation will lead to fewer continuation lines if you limit line length, and code with fewer continuations is easier to read. I do indent code within an if block or do loop, as shown here. I also recommend against indenting code just because it is in a procedure or in the main program. Regarding coding style, should I indent the codes below contains? ![]()
