Examples

<!------------------------------------------------------------------ 
This example shows the use of IsBinary. It assumes that another page
in a syndication program has passed this page the value of the variable 
data_var, which can hold either character data or binary data. This 
example checks to see whether data_var is binary, and if it is, it
converts the binary data into Base64 data.
