If you have many of these types of operations to do you might consider a custom informat.
proc format library=work; invalue missingtext . = 0 other=1; run; data example; x= ' '; yx=input(x,missingtext.); z='anything'; yz=input(z,missingtext.); run;
This informat looks at an input string, if it is missing then the result is 0 anything else is 1. Even if the input string has a leading blank the result is one.
For your use then you would have
NOTE this works if you are interested in knowing that your variable has some text.
