No. you cant create and use a macro variable with in the same data step.

Re: Macro variable and DATA step

The SYMPUT routine assigns the value of the macro variable during DATA step execution, but the macro variable references resolve during the compilation of a step or global statement. So you can’t retrieve the macro variable’s value in the same DATA step in which the SYMPUT routine assigns that value.

Instead of a macro variable you could use a retain statement to keep a value of a variable across iterations of the data step.

While it actually is technically possible to create and then use a macro variable within the same DATA step, it is rarely the right solution. We would need to see more of the problem to address the design issues.
