hi all, due to work and travelling, I have been unable to work on the new version for couple of weeks, but I am returning to the track. I'd like to ask an open question from list members that concerns the variable substitution process. Currently, the variable is not substituted if it either does not exist or is undefined (i.e., has Perl 'undef' value). In other words, if there is a string "$1-$2" with match variable $1 having the value "aaa" and match variable missing, the resulting string is "aaa-$2". Would it be a better solution to replace non-existing match variables (and also non-existing %<alnum> variables) with an empty string instead? The current approach allows for easy detection of unset variables (which might be the result of a type in conf file). However, replacing non-existing and undefined variables with empty strings is more similar to behavior of unix shells (and thus more familiar to end users). What do you think? kind regards, risto
