In SAS Enterprise Guide 4.1, you can define parameters which you prompt
users for values to pass into code, query, or tasks. If you reference a
parameter value in a code node, there are situations where the value
might not resolve properly, or you might see one of the following error
messages:

   ERROR 13-12: Unrecognized SAS option name, value.

   ERROR 22-322: Syntax error, expecting one of the following: a name, a
   quoted string, (, /, ;, _DATA_, _LAST_, _NULL_.
   ERROR 202-322: The option or parameter is not recognized and will be
   ignored.

The problem might occur when you pass the prompted values as a
concatenated value in your code window such as the following statements:

   options set=tcpsec &userid..&pw;

   signon &host..&server user=&userid pass=&pw;

   data my_&testvar;

To submit a statement containing concatenated values, you will need to
modify your code to remove any masked characters using the %UNQUOTE
function such as in the following examples:

   options set=tcpsec %unquote(&userid..&pw);

   signon %unquote(&host..&server) user=&userid pass=&pw;

   data my_%unquote(&testvar);
