Hi all,
The code is :

options sgen;
%let one = two;
%let two = three;
%let three = four;
%let four = last;
%put &&&&&last;

Output is :

357 %put &&&&&last;
SYMBOLGEN: && resolves to &.
SYMBOLGEN: && resolves to &.
SYMBOLGEN: && resolves to &.
SYMBOLGEN: && resolves to &.
WARNING: Apparent symbolic reference LAST not resolved.
&last

Now i want, if SAS doesn't find the Macro variable "last" then
instead of WARNING:, it should display ERROR: message and it should
not print the output as "&last" .
Is there any way that sas will not output "&last' in the log ??
Please help.
Thanks in Advance.

Thanks and Regards,
Amar Mundankar.
