Getting error while assigning library in a macro

[Aditi24]

%macro test(s_no=
,libname1 = 
,libname2 = 
,libname3 = 
,libname4 = 
);
libname inputt "&libname1";
libname interim "&libname2";
libname output "&libname3";
libname dataa "&libname4 ";
%mend test;
%test(
s_no=1234;
,libname1 = C:\Users\abc\Desktop\input; 
,libname2 = C:\Users\abc\Desktop\interim;
,libname3 = C:\Users\abc\Desktop\output;
,libname4 =C:\Users\abc\Desktop\test;
);

I am getting 
Note: Library doesn't exist error while running this code. Please let me know what am I doing wrong.

Drop the semicolons in your arguments like this

%macro test(s_no=
,libname1 = 
,libname2 = 
,libname3 = 
,libname4 = 
);
libname inputt "&libname1";
libname interim "&libname2";
libname output "&libname3";
libname dataa "&libname4 ";
%mend test;
%test(
 s_no = 1234
,libname1 = C:\Users\abc\Desktop\input 
,libname2 = C:\Users\abc\Desktop\interim
,libname3 = C:\Users\abc\Desktop\output
,libname4 = C:\Users\abc\Desktop\test
);

Omit the semicolons after the macro parameters. Those semicolons otherwise end up as part of the directory names.

%macro test(s_no=
,libname1 = 
,libname2 = 
,libname3 = 
,libname4 = 
);
libname inputt "&libname1";
libname interim "&libname2";
libname output "&libname3";
libname dataa "&libname4";
%mend test;
%test(
s_no=1234
,libname1 = C:\Users\abc\Desktop\input
,libname2 = C:\Users\abc\Desktop\interim
,libname3 = C:\Users\abc\Desktop\output
,libname4 =C:\Users\abc\Desktop\test
);
