How can I access the variables in my script ($main::var)

[Sean]

Hi Folks,

I need to access some of the variables in my script. These variables are
used by methods called in packages that might be nested.
I have used $main::var. This does not seem to do job. Any sugestions?

Thanks,

Sean

What script?

We cannot help you with code that we cannot even see.

Have you seen the Posting Guidelines that are posted here frequently?

What does "not seem to do job" mean when you say it?

That is, what did you observe that led you to conclude that it
is not doing the job?

Delivering a diagnosis without being told any of the symptoms
is futile.

Any sugestions?

I suggest providing enough information so that we can help you.

Sounds like a really good recipe for a really bad idea.

When I need to be able to write to variables in the main code block, I
pass them into the modules' subroutines as references. If a nested
routine needs access then pass the reference on to it via its
parameters.

I never attempt to refer to them directly because then it's another
spin on abusing globals and that's not good maintenance-wise.
