[BrahmanandaRao]

Can we print pattern like below using SAS

* 
* * 
* * * 
* * * * 
* * * * * 

[PeterClemmensen · Accepted solution]

data _null_;
   do n=0 to 4;
      a=repeat('* ', n);
      put a;
   end;
run;

prints 

*
* *
* * *
* * * *
* * * * *

Thank You 

Brilliant Code

[Kurt_Bremser]

Yes.

Spoiler

data _null_;
file print;
length text $100;
do i = 1 to 5;
  text = catx(' ',text,'*');
  put text;
end;
run;

[BrahmanandaRao]

Thank You  sir

very impressed your outstanding  coding skills

[Ksharp]

Just have some fun.

data _null_;
   do i=1 to 5;
      do j=1 to i;
        put '* ' @;
	  end;
	    put;
   end;
run;

And another approach:

proc format library=work;
value stars
1='*'
2='* *'
3='* * *'
4='* * * *'
5='* * * * *'
;

data _null_;
do i = 1 to 5;
  put i stars.;
end;
run;

Though harder to maintain if you need a 20 row lower triangle.

Thank You sir

[BrahmanandaRao]

Thank Your

what if right angle triangle  

[Kurt_Bremser]

Do a little thinking for yourself: how can you fill a character variable from the rear?

[Ksharp]

Sure. Not a big deal .

data _null_;
   do i=5 to 1 by -1;
      do j=5 to i by -1;
        put @(2*j) '* ' @;
	  end;
	    put;
   end;
run;
