I didn't port it from vax pascal.
in fact, I've never done any vax pascal programming in my life.
I ported it from vax fortran to turbo pascal. yeah, that was fun, not.
but now I want to move my new code back to the vax in whatever language.
vax basic is the one I'm most familiar with, followed by DCL
the free pascal code is on the order of several hundred thousand lines of
source code.
it's become quite a beast over the decades.
maybe I'll spend the next 38 years porting it back 😊
Dan.

Despite porting the program from VAX Pascal to various flavours of other
Pascal, it seems you don’t recall much about the language.
Moving from Pascal to BASIC would be quite an exercise.
In VAX Pascal the reserved identifiers INPUT and OUTPUT refer to SYS$INPUT and
SYS$OUTPUT, respectively.
Here’s a simple program which prompts for user input.
program hello(input,output);
var s : varying [80] of char;
begin
write('What is your name? ');
while not eof(input) do
begin
readln(s);
if length(s) > 0 then break;
write('What is your name? ');
end;
writeln('Hello ', s);
end.

I found a hello world pascal example online for vms,
so at least that much I can get working.
however, all the docs online are not so useful for programming itself.
my code has input and output from the terminal and from files.
the hello program uses: program hello(output);
so not sure how to do in and out from the terminal.
tried googling examples but no such luck beyond hello world.
it might be easier for me to port to vax basic, I used to be an expert at that,
many moons ago.

Umm, I just looked back at some Pascal code I had on VAX
Pascal, and it DEFINITELY has writeln statements in it.
This is such basic Pascal syntax, I can't imagine that did
not work. But, maybe you have to enable some library or
Pascal "unit" to use those functions.
