[Pgubook-readers] exit program

[Richard Wright]

In an effort to ensure that the code has the file name exit.s, I have tried 
running it like this:

#/bin/sh
#as -o exit.s
.section .data
(etc)
#as exit.s -o exit.o.

It REALLY didn't like that one! It printed off around 50 error messages most 
of which were along the lines of

"junk at end of line, first unrecognised character valued 0x8"

Also

"unknown pseudo-op: `.symtab"

And

"invalid character (0xffffffbb) in mnemonic"

What I was hoping for was by running the assembler and telling it to put the 
output in exit.s I would then have the exit.s file  containing the exit 
program, rather than it just being an empty file as I suspect it is at the 
moment.

I know that my computer will run this program, since I had it working at one 
stage. It was a total fluke, so to find out how I did it, I tried it again, 
except with a differnt value in the %ebx register. Since then I haven't been 
able to get it to work. I would say Ive done everything as I did the first 
time, but obviously I'm not because otherwise it would be running.

You may be onto something with the desktop. Thing is I can't see any "save 
as" option or similar. All that happens on the desptop is after I enter
as exit.s -o exit.o
(file exit.s does not exist)
the exit.o file appears in the file manager window. After linking the exit 
program appears as an executable. It does what it is designed to do, just 
for all the wrong reasons.

can you clarify naming procedure at all?
