Hi everyone,
In a macro I concatenate multiple levels. Seems that one of thats levels have a "%", as a separator i use "#" character and I get differents outputs depending on if I put or not " ".
Here an example
%let var=Test;
%let array=%;
%put &array.#&var.;
%#Test#Test
%put &array.# &var.;
%# Test
%put &array. #&var.;
% #Test #Test
Someone know Why this odd performance? It seems a strange performance that is not presented when there is not the "%"
Thanks
Hi @arodriguez,
Once you have come to gripsd with th emacro facility this behaviour will no longer seem strange. The % sign is what's called a type 3 macro trigger. It has special meaning for the macro facility and will throw things off if not properly stripped from that meaning.
Try coding
%let array=%nrbquote(%);
and your code will run a lot better. (edited from %nrstr(%%) to %nrbquote(%) which is even better)
For background I suggest you read up on macro quoting, an advanced subject indeed. But there are many good resources om the web.
Hope this helps,

The question really is why are you doing that, are you trying to make unreadable code?
