what is the problem?
%macro b(condition);
%do i = 1 %to %sysfunc(ifn(&condition., 2, 3));
%put &i.;
%end;
%mend;
%b(0);
%b(1);

this seem to work, though.
ERROR: There is no matching %IF statement for the %ELSE.
%IF is in a location in a %DO statement where it is not allowed.
ERROR: A dummy macro will be compiled.
You macro named %A has not been compiled and so cannot be used.
This, however, would work, as now the %IF is in a position where it is recognized. (Your %b is another way to make this work)
%macro a(condition);
%if &condition. %then %let endvalue = 2;
%else %let endvalue=3;
%do i = 1 %to &endvalue;
%put &i.;
%end;
%mend;
