How do I pass two long strings to a macro?

[MarkGreenaway]

I want to pass two long strings into a sas macro, like this:

%some_macro(first=this is quite a long string, two=and so is this);

I can define macros where I pass an argument like the first, but if I have two arguments like this it seems SAS gets confused, and I get errors about strings being 262 characters or longer. I suspect I should be using some sort of quoting or something, but I'm not sure exactly what to use. Any ideas?

Mark,

It would help if you posted an example of code that produces the error.

[MarkGreenaway]

%macro

two(first=,second=);

title

"&first &second"

;

proc freq data=hsurvey2.hsa05_adult_public;

table year;

run;

%mend

two;

%two(first=this is a long string, second=and so is this);

It turns out that this works fine. The problem in my code is something else entirely. I'll try to track that down.

There is a limit on the length of a macro variable.  Should be around 32,000.

The error message you report can be suppressed by using the option NOQUOTELENMAX.

You would see it if your macro did something like.

data out;

   var1="&first";

run;
