In word tags start with backward slash '\'. For Example \tab for a tab.
Let us say I am creating a word doc from another application which prints a
dataset that contains a variable. The variable has backward slash in some of
its values. So when the document was created, I didn't see anything after
backward slash. How can I mask backwardslash from disappearance in the word
doc.

Here is an example :

My name is abc \tab and my apt is new \good.

When the application creates the word doc, it should appear like

My name is abc                 and my apt is new \good.

But it appear as

My name is abc                 and my apt is new

So if you see here '\good' is missing.  This is happening because 'good' is
starting with '\'. Since tags start with '\', whatever after '\' will
disappear(I guess). And my application to create word doc is SAS(Statistical
Analytical Systems). How I can avoid this i.e. \tab should work and \good
appear in the word doc.
