SUPPORT / SAMPLES & SAS NOTES
Problem Note 43828: The error "Expecting a variable name after %LET" occurs in SAS® 9.3
 |  |  |  |  |
The %LET statement in SAS® 9.3 might fail, resulting in the following message in the SAS log:
ERROR: Expecting a variable name after %LET.
This problem is most likely to occur when the %LET statement is defined within a macro that is called by another macro. Here is an example that replicates the problem:
%macro foo(arg1);
%put This is FOO! &=arg1;
%mend foo;
%macro bar;
%foo(%let x = 1; &x);
%mend bar;
%bar;
