Interface read_line

Read a line of text from a file (up to a line break, or 1024 characters). This can then be parsed by the calling routine (using parse_line for example)

Optionally, a status is returned which is:

• $<0$ if the end of the file is reached
• $=0$ if no problems were encountered
• $>0$ if there was a read error

The actual number returned is implementation specific

this -- type(Inoutput), intent(in)

status -- integer, optional, intent(out)

Return value -- character(1024)
