K&R C, fortran keyword
Tim Shoppa
memory... correct me if I'm wrong...
the conclusion was, "fortran" is a reserved keyword in K&R C, but no
compiler ever actually did anything with it? (Unlike say "asm" which
actually did something on some compilers).

Yes. The intent was to put out a marker in case we wanted
to put in an interface for specifying a Fortran calling sequence,
but this didn't happen (here, anyway).

The early Microsoft C/C++ compiler (1991) supported __fortran as a keyword
to control the order in which arguments were pushed in a /call/ statement.
From the reference manual which somehow is still on my shelf...
__pascal, __fortran
Specifies that the associated function is to be
called using the Pascal or FORTRAN callling
convention (arguments are pushed from left to
right). The __fortran and __pascal modifiers
are synonyms.
The __fortran and __pascal keywords are not
accepted for 32-bit targets.
I don't have a nearby copy of K&R (sorry, Dennis...) to know if this was the
intent of the reference you're citing.

Yes. VMS has a calling standard.

So does windoze. In fact, it has several of them.

Having more than one rather obviates the point, no?

Sure, you can call Windows by many names ;-)

Given the fact that the name of this proud Microsoft product was
somewhat misspelled I guess that his tongue was firmly stuck in his
cheek ;-)

Did PLAN handle call by name as well, or was that mechanism reduced to
call by reference?
The Burroughs/Unisys MCP supports a calling standard too. In fact it
allows you to combine seperately
compiled subroutines written in diferent languages into one
executable. This was done by SYSTEM/BINDER,
a neat tool that even allowed you to replace subroutine modules in an
existing executable so you didn't need to recompile
the entire program. BTW the binder was not a linker, the MCP has no
need for a linker (nor an assembler).

Each parameter was represented by an instruction that determined its address
or value, as appropriate, compiled in a sequence of N orders for an N
parameter routine, following the "CALL X S" instruction.
Parameter P was obtained from within S by the instruction "OBEY P(X)" where
OBEY is an execute-type instruction that causes the operand to be executed
as an order.
For a simple value- or reference-parameter, "OBEY P(X)" would be done once
by the subroutine, and the OBEYed instruction would be a simple load into an
ABI-defined register. For a name parameter, the OBEYed instruction would
itself be a subroutine call, to a thunk, with the same ultimate effect.
Value-, result-, value-result-, reference-, lazy- and name- parameter
policies can all by obtained by this mechanism (in the case of name by
OBEYing the thunk on every use of the formal parameter).
Return was by "EXIT X N", which jumped back to the point after the Nth thunk
order.

I like the both of them. Here is another in the same vein:

That's what I was thinking... so I googled it up...
Seems I paraphrased his actual quote:
"I love deadlines.
I like the whooshing sound they make as they fly by."
