Re: strange behaviour of dbLoadtemplate

[Luedeke Andreas WSLA/209 <Andreas.Luedeke@psi.ch>]

Hi,
the problem can be solved by replacing the single quotes in the substitution file with double
quotes.

Is there any "lex" expert listening who knows why?

Andreas

PS: is it a desired feature, that escaped characters are only handled in substitution files but not
in templates?
