Hey Chuck, send me an email off-list
Vax fortran in the 70s was kind of an interesting time,some of it was Fortran-IV, some of
it was Fortran-77I don't remember any of the things that makes those different or how
to distinguish them.
I have some code from that time that would compile "back in the day",but that
same exact piece of code will NOT compile on vms 7.x with the compaq compiler.
It's almost like I need to have a system running vms 4.2 with the fortran of the time
to get it to work.I have to assume the resulting binary would work on modern systems?
I have some classic game source code from the time I want to get back online and in the
archives
Fred - I have a 16.2MP Sony digital camera I could use for "scanning" but doing
that with a printoutthat is 6" thick will take an obscenely long amount of time.
I don't want to separate the pages, I have this massive fear that as soon as I do,
they will get out of order...
Dan.

I don't think I could ever forget how--I spent too much of my life
working on FORTRAN compilers.
I got the DEC PDP-10 source code for Adventure from a DEC field
engineer about 1974-75 on a reel of 9-track tape (don't laugh--we
were still heavily into 7-track). I was surprised to see that it was
text packed into binary form--3 7-bit ASCII characters per 36-bit
word (you'd have thought that if it was character data, it'd be one
character per tape character); converted it to 6 bit display code and
unraveled the DEC-10-specific FORTRAN constructs into their CDC 6000
versions (harder than you'd think, particularly with Hollerith
constants); transformed the database to be readable by 6000-series
FORTRAN I/O and I was off and running.
You have no idea how much company computer time was wasted on that
thing. The COMSOURCE admins used to conduct sweeps of employee
permanent files and purge every copy they could find.
So, if this is anything like that DEC 10 version, I can probably
lend a hand...
