Re: Anyone for help with DEC (Vax) Fortran-IV ?

Jim <j.n@xxxxxxxxxx> wrote:

As for the printed copies, you need to understand that VAX Fortran allowed a
Tab character at the start of a line to move the carriage to position 7
which is where the source code should start. When printed, you cannot tell
that the Tab replaced several blanks. Hence what looks like a line of more
than 72 characters may not have been that long.

That's one of the multiple reasons that tabs cause portability issues
even among compilers that accept them. Since they are not standard, the
fine points of their interpretation can vary. This includes such matters
as whether the tab counts as 1 character or as the multiple expanded
blanks.
