Array Error ? Var_Char = put(Var_Num,3)?

[ybz12003]

Hello,

I have error messages shown in the log window when I try to do an array.  Please help; thanks.

data ds2;
set ds1;
array Var_Num{i} hcsfpcrothresult  rapidrsvothersp ;                                    
array Var_Cha{i} hcsfpcroth_result  rapidrsvother_sp ;                                      
 do i = 1 to dim(Var_Cha);                                      
	  Var_Num{i}=put(Var_Cha{i}, 3.); 
drop Var_Num{i}; 
 end;  

run;

I think it is good advice for you to show us the ENTIRE log for this DATA step, not the portion you did show us. 

In ARRAY statements, you put the number of elements inside the curly brackets, not a variable name like you did.

The log tells you the array declarations are wrong.

data ds2;
set ds1;
array Var_Num(2) hcsfpcrothresult  rapidrsvothersp ;                                    
array Var_Cha{2) hcsfpcroth_result  rapidrsvother_sp ;                                      
 do i = 1 to dim(Var_Cha);                                      
	  Var_Num{i}=put(Var_Cha{i}, 3.); 
 end;  

drop hcsfpcrothresult  rapidrsvothersp ;
run;

You are not defining the array properly.  You don't have to tell SAS how many variables are in the array when you have listed the variables explicitly. SAS can count.

array Var_Num  hcsfpcrothresult  rapidrsvothersp ;
array Var_Cha hcsfpcroth_result  rapidrsvother_sp ;

If you want you can waste your time and specify the dimension then use either the actual dimension or a *.

array Var_Num [*] hcsfpcrothresult  rapidrsvothersp ;
array Var_Cha [2] hcsfpcroth_result  rapidrsvother_sp ;

You cannot drop an array. Only the actual variables.

drop hcsfpcrothresult  rapidrsvothersp ;

Note: If you want to list a variable in the dimension of the array definition then you have to use regular parentheses instead of either square or curly brackets.  But then you are defining an array that must index implicitly instead of explicitly since the variable name you put is the name of the variable that will be used to index the array

data ds2;
  set ds1;
  array Var_Num (i) hcsfpcrothresult  rapidrsvothersp ;
  array Var_Cha (i) hcsfpcroth_result  rapidrsvother_sp ;
  do i = 1 to dim(Var_Cha);                                      
     Var_Num=put(Var_Cha, 3.); 
  end;  
  drop hcsfpcrothresult  rapidrsvothersp ;
run;

Create a value and then attempt to drop it?

Put a value, which creates character values, into what appears is intended to be numeric value?

Maybe describe what you intended to do, i.e. provide example values and the output.
