print *, 'Data written to ', trim(filename) end program write_binary_file 代码解释 文件名和单元号: 定义文件名 filename 和单元号 unit。 初始化数据: 使用 do 循环初始化数组 data。 打开文件: 使用 open 语句打开文件进行二进制写入。form='unformatted' 表

FORTRAN binary files are not flat.An unformatted FORTRAN binary file contains record length information along with each record. A record is a WRITE statement.The record length information is tagged on at the beginning and end of each record. 下面这段fortran代码有三个write语句,即文件中有三个记录...

binary---即二进制文件。你写入的是二进制文件，你却要用记事本打开，当然就是奇怪的符号！form = 'binary'－－－将这部分删除 ！！！
as I/O list items in WRITE statements referring to the file. binary则只含有数值 使用form=’BINARY’ 打开文件与使用 form=’UNformATTED’ 具有大致相同的效果,所不同的是文件中没有嵌入记录长度。如果没有此数据,则无法知道一条记录的开始或结束位置。因此,无法对 form=’BINARY’ 文件执行 BACKSPACE 操作...
I am under the impression I can make a binary file that allows random access to a set of fixed size records. Its allowing me to write records sequentially, but if I pick a record number, I cant do that. for example if I have 100 records of 20 integer words each, I should be able...
