macro call result error with % sign

abhinayingole — Tue, 31 Oct 2023 10:56:33 GMT

%macro chk (result = );
data one;
val = "&result.";
run;
%mend chk;

%chk (result = %str(Intensity (%)) );

I need to print result for VAL variable as "Intensity (%)" ,e.g VAL = "Intensity(%)" , but not able to do it with above code.

any suggestion please.

When you use %STR(), you can mask a % with a %, so use %%. See the docs: https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/mcrolref/p0pnc7p9n4h6g5n16g6js048nhfl.htm

Example Log:

1    %macro chk (result = );
2    data one;
3    val = "&result.";
4    put val= ;
5    run;
6    %mend chk;
7
8    %chk (result = %str(Intensity (%%)) );

val=Intensity (%)
NOTE: The data set WORK.ONE has 1 observations and 1 variables.

For this example, you don't actually need any macro quoting, you could just use:

8    %chk (result = Intensity (%) )

val=Intensity (%)
