Have you run PROC CONTENTS?

I haven't used it, but perhaps NOTDIGT() is a possibility:

 

184  data _null_;
185    input text $;
186    if notdigit(trim(text))=0 then num="Y";
187    else num="N";
188    put (text num)(=);
189    cards;

text=hello num=N
text=123 num=Y
text=1 num=Y
text=4,321 num=N
text=1.5 num=N
text=m1m num=N

196  ;
197  run;

 

 

I think that should work, nof by numeric you mean contains only numbers.  As shown above, characters such as comma or decimal point are considered non-numeric.

 

Kind Regards,

Clearly, this code will rarely work.  It examines the first three characters in your variable to specifically see if the first character is a digit and the second and third characters are both blanks.  I doubt that is what you wanted to accomplish.

 

What did you want to accomplish?  You will have to explain it in words, rather than show code that doesn't work.
