Josune- If what you're really trying to do is create macro variables (MBETA0-MBETAn) whose values match corresponding datastep variables (BETA0-BETAn) you made it much more difficult than it needs to be. Try something like:

%let NumVar = 5; data _null_; beta0 = -7.687; * intercept; beta1 = -0.0251; * age; beta2 = 1.8990; * sex; beta3 = 1.7412; * chestp1; beta4 = 0.7849; * chestp2;

array beta(&NumVar) beta0-beta%eval(&Numvar-1);

do i = 1 to &NumVar; call symput('mbeta'||left(put(i,2.)),put(beta(i),7.4)); end; run;

%put &Mbeta0; %put &Mbeta1; %put &Mbeta2; %put &Mbeta3; %put &Mbeta4;

This should give you what you need.

Hello, SAS-Lers!

I 've got a problem. I want to give to some macrovariables the values of some variables in order to use them later. I have tried with the code below but the value of the macrovariable is always the same, the name of the variable not its value. I want to know what is wrong with the code.

Thanks in advance,
