WebTraditional FORTRAN environments usually assume carriage control on all logical units. They usually interpret blank spaces on input as zeroes, and often provide attachment of global file names to logical units at runtime. The routine IOINIT(3F) can be called to specify these I/O control parameters.

Once you hit Ctrl-D, the system would consider your input stop at there. If your program tries to read passing this point, this is an error. However, with IOSTAT=, you can catch this end-of-file mark and do something about it. dobhoff tube clogged
