Need Help??

Your regex test

$DB_name =~ /[ISWLIVE ISWTEST ISWTEACH]/
[download]

should really be

$DB_name =~ /(ISWLIVE|ISWTEST|ISWTEACH)/
[download]

And then later...

each %$DB_name
[download]

I would create a reference to hash with:

$HREF = eval "\\\%$DB_name";
...
if ($HREF->{key} ...)
[download]

`$HREF = eval "\\\%$DB_name";` Ouch. Please don't do that! And if you do, please check `$@` afterwards since eval will trap fatal errors silently. -sam	[reply] [d/l] [select]

Thanks - I think you just helped me solve a different problem. Checking $@ showed where my script was bombing.	[reply]
