@Carl Love

Great work - will give credit to you in case I use it.

Best regards,

Oliver 

@acer Great thing - easy fix....

@ecterrab Thanks a lot for the information - which is a bit disappointing, though.

My main interest is to transfer a big worksheet into a Latex script, which needs constant updates - so the suggestion is not really practical for me.

Best regards,

Oliver

@acer: Thanks a lot - assign as a command is what actually I will be using.

@Preben Alsholm: Thanks a lot - tricky indeed
