Re: Reg:Character or Numeric variable

If you want to know how a column is defined, that information can be reached in DICTIONARY.COLUMNS (via proc sql), SASHELP.VCOLUMN or data step functions. The can assign that value to a macro variable to be used in an assignment statement.

if you want to know what type of values is stored in a character column, there's a bunch of functions that can helpful such as notdigit.

Re: Reg:Character or Numeric variable

Depending on the purpose/use of a given SAS variable, you can define whether it is CHARACTER or NUMERIC type (using either a LENGTH or ATTRIB statement) or with one of multiple "import" processes, and also you should define what SAS output FORMAT is to be used to display the data.

Hi Main,

With PROC CONTENTS, you can use the ODS table "Variables" to save the variables' types as a separate variable. Please look at this example:

data test;
input var1 $ var2 var3 $;
wqw 83478 360376
febifie 947604670 305035
bdhb 045670 230948

proc contents data=test;
ods output variables=var_type;

proc print data=var_type;
