Bernd,  
Get rid of the 'then' in your 'if' statement -- it is not part of the
'if' clause syntax.

	dear all, 
	what is wrong with this?
	
	
	ignore=(20101021)

	* check current date against list of dates to be ignored:

	for the life of it, skip is always true! even if skip is
anything but
	zero!
	
	What can I do to skip if skip =0?
	
	Cheers,
	Bernd.
