Mindy ,

Use input function to go from character to numeric and Put function to go
from numeric to character.

Data Try;
Num = Input( '123' ,  8. ) ;
Run ;

Proc Print
  Data = Try ;
Run ;


Data Try ;
  Num = Put( 123 , 8. -L ) ;
Run ;

Proc Print
  Data = Try ;
Run ;

Hey guys,

I play with input function, but feel confused about some questions:
(a)
data try;
  num=input('123', 4.);
run;
proc print data=try; run;

(b)
data try;
  num=input(123, 4.);
run;
proc print data=try; run;
(a) runs correctly, which give me output as num=4.
(b) give me a note as numeric value has been converted to character
value, which is expected. The unexpected thing is the output is num=.,
which means SAS doesn't really do numberic value to character value
converting as it said in the note.

Any one know why?
Thanks.
Mindy
