Tommi, I had some compiler errors but it was trivial to fix them.
Thank you very much.
Just a follow up-question:
How can I conditionally execute such a construct:
<p>content of record <$ currentPos $>: <$ myVector[currentPos] $></p>
For example in pseudo-code ("int format" is a session var):
if (format == 1)
<p>Using format 1: content of record <$ currentPos $>: <$
myVector[currentPos] $></p>
else if (format == 2)
<p>Using format 2: content of record <$ currentPos $>: <$
myVector[currentPos] $></p>
else
<p>Using default format: content of record <$ currentPos $>: <$
myVector[currentPos] $></p>
Is something like that possible to do?
