BASIC script access to /dev/stdin,stdout,stderr

Mike Henderson — Tue, 21 May 2002 13:52:18 GMT

We have a third-party application
developed on a different platform. It
is transportable to many platforms, but
in the case of HP, it has an issue. It
is written in BASIC and requires
(normal functionality) access to stdin,
stdout, and stderr, which it cannot
access directly internally by device
number. This is accomplished by
referencing /dev/stdin, etc on other
systems but HP doesn't have these files.
How can this be accomplished on HP?

Have you tried creating named pipes for /dev/stdin, etc.? Also, could you post how you would initiate running the BASIC program?

Try to link /dev/tty

to /dev/stdin /dev/stdout /dev/stderr

ln /dev/tty /dev/stdin

See on others systems is that files are linked to anyother specila files and check if major and minor for /dev/stdin are equal to anyothers in /dev.

Just thinks.

Thank you for your very prompt replies! I apologize for the delay in response, I've been out of town AND have not received a test program from the vendor to test your solutions (They are rather over-protective of thier software). This uses Thoroughbred basic and would be normally be executed via a statement similar to "./b IPLNAME", where the IPLNAME is the 'template' that assigns the devices. They have moved the task to a (Caldera) server that does not have this issue to resolve. I would still love to test this to see why they couldn't get it to work!
