Array.

Hello to everyone; please help me to write a program to Take n’th character from n’th word and keep in separate variables using arrays.

Take n’th character from n’th word and keep in separate variables

[PaigeMiller]

Show us what you have tried so far.

Also, I'm not really clear what that means: "Take n’th character from n’th word and keep in separate variables". Can you give examples?

And why do we have to do this with arrays?

[SASbeginner4]

There is a string, for example, "I had been caught going through a traffic light on the change." and there is necessary to keep every letter as a variable, for example var1 var2 var3 var4 and so on till the end.

                                                                                                             I         h       a       d                                                           

[PaigeMiller]

Why? I can't really see a point to taking a text string and separating it into individual letters.

And I ask again: show us what you have tried.

So if the source variable has a length of 200 you will need 200 new one character variables.

data want;
  set have;
  array c [200] $1 ;
  do i=1 to lengthn(string);
     c[i]=char(string,i);
  end;
run;

What will you do after you have this likely to be obnoxious number of variables?
