Code for Arrow (Text)
Hello,
I am creating a table, and in the table I would like the symbol of an up arrow, and down arrow, I cant find the symbol code in eviews, if I copy paste an arrow from a website, I will get a "?" symbol. This is all for eviews programming

Table.setformat(#column) p.0
Hi,
I would like to know if it is possible to include the "%" icon when I format a column in a Table. For example>
Table.setformat(B) p.0
It gives me the #number, instead of the #number%, like 23, instead of 23%, I want to show it is a percentage.
Thanks

Normalize
Hello
Is there a function to normalize series to 0 (zscore)? or do I have to do it manually as (@last(x)-@mean(x)/@stdev(x))?
thanks!
