I run the code again, did not see any warning message. But the title is not shown in the html output window. I don't know why. What is warning you got?

I got it. &num in the title statement will be returned as '1'  '2'  '3', which cause the warning in the log window. After removing &num in the statement, there is no such error.

I did several modification with your code to fit my program. and it works great. Thank you very much.

It is good you made it works. I am still not sure why tiele&num got a warning.  It is seems that the title does not need a numer in your case.

I do not have any warning error. somebody else try the program.  I think his problem is there's space between title and &num.  From his log, title1 was transfer to " title    1".

Sorry. The previous explanation was not the key.

The real problem is caused by   call symput('num', num); The numeric values have been converted to character values. In the case, SAS will automatically add several spaces before the num value.

When you replace it with call symput('num', put(num,1.)), there is no warning in the log window.

You are right. Thanks for let me know that.
Acturally, I found the number in the title strange, so I removed &num in the saved code. That is why I did not found the message at second run.

I am learning Macro now, and just learned that call symputx which added for SAS9.1 and later can used to remove all the spaces. I tried and it works.
