I want to run a macro that takes a dataset, processes it, and outputs a new dataset with a that name depends on the name of the original dataset.
e.g something like this
%let data_in = my_data;
%let data_out = &data_in || '_processed'
But calling &data_in isn't really what I want to do, I would like call the dataset name as a character string. Is this possible?
I've had a hunt through documentation and forums but can't find what I am looking for.
Don't use quotes in macro language if you want to concatenate strings. Always keep in mind that macro language is most and foremost a text processing tool, and only knows the data type character.
Do it like this:
%let data_in=my_data;
%let data_out=&data_in._processed;
The dot after the &data_in terminates that particular macro variable reference.
PS if you use quotes in the right side of a %let, they will become part of the value stored in the macro variable, instead of being treated as string delimiters.
