Of course, since I've only just released the software, the questions are yet to flood in, so to get things started I though I'd address some of the more esoteric aspects of Zonk.
<qs> I cannot get date formatting to work. Whenever I try the output is always just the format string I've used, none of the parts starting with '&' have been substituted.
<as> You are forgetting to put the 'treat as' modifier, '@' to indicate a date, on the end of the variable name. Thus the format is being treated as a string format and unless it contains a '%s' won't give your variable's value at all.
<qs> I am trying to print a number which can be in the range 0-100 with leading zeros, I'm sure I've got the format right (%3.3d) but I'm just getting garbage as output.
<as> The modifier to tell Zonk to treat the variable as an integer '#' is missing from the end of the variable name.
