This is a binary file, data is stored exactly as in memory. Thus, it is shorter than an equivalent formatted file, and access is faster.
However, such a file can only be read by a Fortran program on the same type of system as it was written. Lengths of records can vary. Except that the first record stores the total number of records. Note that it is necessary to store the length of a variable-length record before the variable data, so that it can be read in time to control the implied DO loop.
In this example, a Medical lab that does blood tests registers patients with a patient number starting with 2. They want to be able to print the current patient list, and also access patient name, etc directly by number.
Note that we are using the first line to identify the file, and keep a count of the number of patients registered, which is also used and updated when adding new patients. Subsequent lines all use the same format.
From this we calculate the record length, adding 2 bytes for end-of-line character codes. We first set up a file with only the header record: Next number to assign!! Of course, it might also be a good idea to check that the health insurance number does not already occur in the file.
We will skip around, reading record 1, writing a new record, presumably at the end, and finally writing an updated record 1. The intervening records do not have to be processed.
It could check to see that the number is valid, by also reading record 1.
They need not be identical, as long as they interpret the same columns of data consistantly. Such files are characterized by fixed size records and fast, direct access by record number. There is no conversion between internal and external representation of data, so in particular, no accuracy is lost when storing REAL data.
For example, the same medical lab of our formatted-direct example receives blood samples, which are numbered sequentially in the "Incomming Blood Book".
Later, when the test results come in, we will consult this file and the patient file and a Doctor file to prepare a report for the Doctor. First, here is the subroutine to record incoming blood.
By adding up the space required for the WRITE statement, we find that 16 bytes are needed for each record fewer for record 1. Actually it is desirable for record length to be a power of 2.If ACCESS='APPEND': SEQUENTIAL and FILEOPT='EOF' are assumed. This is for opening a file to append records to an existing sequential-access file.
This is for opening a file to append records to an existing sequential-access file. In Fortran 95, using the TR introducing ALLOCATABLE arguments of SUBROUTINEs, I can write a subroutine to append elements to an ALLOCATABLE array as shown below, but it looks inefficient, with all the ALLOCATEs and DEALLOCATEs.

Excel is one such system.
Separator. A common field separator to use in the file is a comma, as that is unlikely to appear in any of the fields in English-speaking countries.

Write a Fortran program which will create a temporary direct access file, prompt for the name of an existing file and read that file sequentially writing each line to the next record of the temporary direct access file.
