Hi all,
Below is an extract from SAS Publication: SAS Certification Prep
Guide: Advanced Programming for SAS 9.
Page No. 300
**************************************************

Suppose you want to verify the value of the macro variable city. Since
the %PUT
statement resolves macro references in text before writing text to the
SAS log, you can
use it to show the stored value of city.
%put The value of the macro variable CITY is: &city;
Table 9.3 SAS Log
120 %put The value of the macro variable CITY is &city;:
The value of the macro variable CITY is: Dallas

You can also simply submit the statement &put &city; without any
additional text.

This statement will write the resolved value of the macro variable
city to the SAS log;
however, it will not write any additional text to the log. You might
find that it is a good
idea to add explanatory text to your %PUT statements in order to
maintain clarity in
the SAS log.


***********************************************

It is mentioned that "You can also simply submit the statement &put
&city; without any additional text.".
But when I tried to write &put &city. (City has value Pune).
SAS threw an error:

14 %let city = Pune;
15 %put _user_;
GLOBAL CITY Pune
16 &put &city;
-
180
WARNING: Apparent symbolic reference PUT not resolved.

ERROR 180-322: Statement is not valid or it is used out of proper
order.

Can anyone please tell me can we use &put &city; to display the value
of City macro variable ???
Is there any option we need to set for &put &city; so that City's
value will be displayed in Log?


Thanks and Regards,
Amar Mundankar.

Hi Amar

SAS macro statements start with a '%', macro variables with a '&'

It's therefore %put &city; as in the Cert Prep and not &put
&city;

You used an & before 'put' so SAS interpretes this as a macro variable
- which you didn't define - and therefore the Warning "WARNING:
Apparent symbolic reference PUT not resolved."
