Recently I tried to write a little basic09 program to spool print a letter
I was writing to my family. It was a pretty simple program, I passed it the
path to the file, and the number of copies I wanted printed and it would print
that number of copies. However, it ran through the first iteration and
returned a device
not ready error. I used a for loop to count the number of iterations and the
shell command to list the file to the printer. My question is this, can
I use the close statement after printing the file without using an open
statement before I run the shell command. Should I do something like:
for i = 1 to count
shell ("list " file ">" #printer)
close #printer
i=i + 1
next i
or do I need to have an open statement somewhere? should it be before the
for loop, or should it be in the for loop?
In another area, I just got done taking a class in the UNIX(r) system shell.
(the Bourne shell). It is pretty amazing what you can do with a shell that
is also a programming language. I hope I can put some of this to use in
Basic09. It's too bad we don't have something like that for OS9.

The '#printer' is binary. The best thing to do is to build a character string properly in separate statements and then use it in the shell() call. Something like this: cmd$ = "list " + file + " >/p" shell(cmds$) That's off the top of my head, so there may be a mistake in there, but I doubt it. >In another area, I just got done taking a class in the UNIX(r) system shell. >(the Bourne shell).

Well, yeah, but BASIC09 can make up for a lot of it. But like other areas of OS-9 6809, the thing I find disconcerting is that as good as it is, it could stand improving, and Microware seems to have become complacent about fixing bugs and such. Frankly, I haven't used BASIC09 in a long time, having been using C almost exclusively lately, but in the back of my mind I vaguely remember finding a bug or two. -- Jim Omura, 2A King George's Drive, Toronto, (416) 652-3880 ihnp4!utzoo!lsuc!jimomura Byte Information eXchange: jimomura
