First off, you can use
with the example code. If you actually have 4 long data, you can use the
strip/compress/trim options others have mentioned, or the -L option (so,
put(var_num,4. -L) to left align it.
Finally, I would say that most of the time you should use your user-defined
a) If you really want the characters to be in the variable, do
and define charfmt as a numeric format
or something like that.
b) Usually it's better not to store the character value at all. Simply
define the format as I describe above, and then in the data step, apply the
format var_num charfmt.;
and then it will always appear as 'A', 'B' etc. in procs and when you look
at the data [though be aware some methods of exporting do not preserve
formats]. That maintains the underlying value (the 1,0,etc.) but displays
the value labels.
