Vortex - err if DB not initialized

Post by **Thunderstone** » Fri Sep 10, 1999 2:03 pm

Hello,

I was trying to initialize some variables, assign them some values, etc.
before initializing/connecting to the DB.
The problem is that certain types of assignment cause errors like this one:





The line that causes the problem is the one starting with <$abc ... below:

<SCRIPT LANGUAGE="Vortex">
<A NAME=main PUBLIC>
<$tmpldir = '/tmp'>
<$abc = ($tmpldir + '/abs.html')>
</A>
</SCRIPT>

Is there anything I can do to make Vortex allow me to do this?
The line above doesn't cause problems, so I'm not sure why the $abc one
does...

Is there any way around this? Alternatives?

Thanks,

Otis

Using math in Vortex assignment statements (ones with parens around the
right side) requires an open database handle, thus the error in this
case. The previous assignment <$tmpldir = '/tmp'> does not use math
and therefore did not need to open a database.

Make sure the topmost <DB> directive (above all functions) is pointing
to a database that always exists, so that a valid database can be
opened for math even before <DB> is set in the function.

Or use <sum> instead of + in assignments where the database is not open
or valid yet; this does not require a db handle.
