Hello,
Kindly help me with this task.
I do have a variable with value 'GLOBAL INDIA'
Here, I want to insert '_' for every letter
Output I need: G_L_O_B_A_L I_N_D_I_A
Strange requirement. Below will work as long as you are not dealing with characters that use more than one byte (because the SAS RegEx functions are not - yet? - built for this).
data test;
var='GLOBAL INDIA';
/* define length for new variable doubled the source variable */
if 0 then var_new=var||var;
var_new=prxchange('s/([^ ])(?!\b)/$1_/oi',-1,strip(var));
run;
Looks like homework, what have you tried so far?
Your wanted output does not match the description, there is no underscore after the final A.
If this is type, using a regular expression is my first choice.
