subrat1 — Tue, 19 Jul 2016 20:44:35 GMT

I have two numeric column : COLLISION, COMPREHENSIVE , I want to create one Character Column OTHER_COVERAGE having value 'Comprehensive

if both value are missing or one column is missing and another column is zero then I want to create one Character Column OTHER_COVERAGE having value 'Comprehensive

COLLISION	COMPREHENSIVE	OTHER_COVERAGE
.	.	Comprehensive
.	.	Comprehensive
0	.	Comprehensive
.	0	Comprehensive
.	0	Comprehensive
0	.	Comprehensive
.	.	Comprehensive

What should your new column be if COLLISION and COMPREHENSIVE are both zero?

What should your new column be if some other value (such as 1) is found in one of the variables?

Here is one way:

data want;
   set have;
   if  nmiss(collision,comprehsive) = 2 or 
      (nmiss(collision,comprehsive) = 1 and max(collision,comprehsive) = 0)
      then Other_coverage='Comprehensive';
run;

Comprehensive

So if 0 in both variables also gets you "Comprehensive" then you could do it this way:

if (not collision) and (not comprehensive) then other_coverage = "Comprehensive";
