data have;
input A $ B C $	D ;
datalines;
CA	1	1	1
CA	2	B	1
CA	3	B	9
CA	4	B	8
CA	6	R	2
NV	1	B	1
NV	2	B	1
NV	3	B	1
NV	4	B	1

Provide a more complete example. It is likely to be a variation on what @Kurt_Bremser has already provided.

 

Macro is likely not the way to go though a number of arrays may be needed depending on your rules for which values are used to assign to other variables.

Hi, 

 

I have about 60 variables that need to replace with values from one variable.

This would be an example data set need to replace c,d,e,f,g with values from B.  Thanks ! 

data have;
input A $ B C $	D E F G ;
datalines;
CA	1	1	1 20 7 10
CA	2	B	1 2 5 18
CA	3	B	9 3 5 18
CA	4	B	8 3 3 7
CA	6	R	2 4 2 6
NV	1	B	1 4 1 9
NV	2	B	1 4 1 10
NV	3	B	1 5 7 18
NV	4	B	1 5 4 8
NV	5	B	1 5 4 7
NV	6	B	1 5 6 8
NV	1	R	4 5 7 9
NV	2	R	6 5 8 10
;
run;

Declare one array for character and another for numeric variables. Then use my assignments in do loops for 1 to dim(array), one for the numeric and one for the character array.

Then you need to clarify your logic. You can create an array to loop through multiple variables if needed but given what you've posted there's no need for such a solution.
