This should do the trick:
%MACRO TEST;
 
PROC IML;
 
start mat2macr(macnm,scal);
  /* give macro variable &"macnm" the value of the scalair */
  call execute('%let ',macnm,'=',char(scal),';');
finish;
 
..
X=2;
 
* store the value of the scalair X in the macro variable "&Y";
run mat2macr('Y',X);
..
QUIT;
 
/* Don't need this: */
/* %LET Y=(?? X's value); */
 
 
%MEND TEST;
