Query on auto generation of variable and data

[Lidia1]

I want to generate  a list with 4 variable like - name,age,sex,roll  and want to populate data .

But for doing that I cant use any raw data file. I have to use some auto generating functions here I guess.

The variable will be generated automatically and data will be populated automatically. I can only define starting value for each variable and the number of observation I want.

Kindly help me with such query.

Check the next code:

%let rows = 100;
/* pfx stands for prefix */
%let pxfName = name;
/* numeric values can be computed randomly in a given range 
   using any randomizing function - like ranuni */
   data want;  
     length name $20;  
	 do i=1 to &rows;     
	    name ="&name" || put(i,5.);     
		age = int(ranuni(-1) * 100) + 8;  /* any age 8 and above up to 108 */   
		if mod(_N_,2) < 1 then sex = 'M'; else sex ='F';
        /* add any algorithm to compute roll randomly */		
		OUTPUT;  
     end;
run;
