Hi,

REXX is still quite new for me, so this query- In below examples, where it's written "---> what's the need", what's the difference would be there in the output, of using below snippet without those & with these "extra" SAY statements ?
Code:
 
   SAY ''                                                                ---> what's the need
 SAY 'HOW MANY TIMES WOULD YOU LIKE ME TO GREET YOU?'                   
 /*  ASK USER  */                                                       
 PULL HOWMANY
 DO I = 1 TO HOWMANY                                                     
   SAY ''                                                                ---> what's the need
   SAY 'HI THERE'                                                       
 END                                                                     


Code:
X = 256                                   
Y = 8                                     
SAY ''                                     ---> what's the need
SAY 'X IS' X                               
SAY 'LEFTMOST CHARACTER OF X IS' LEFT(X, 1)
SAY ''                                     ---> what's the need
SAY 'Y IS' Y                               
SAY 'LENGTH OF Y IS' LENGTH(Y)             
SAY ''                                     ---> what's the need
SAY 'X DIVIDED BY Y IS' X/Y               

I used them with & w/o but same results were there. Actually I doubt it, dumb in me is not being able to find the difference I think, please guide..

This is just for writing an empty line to your output device.

Hi O,

Goshh, I removed only the first SAY, so it didn't make any difference in the output on panel..

Thanks O.


PS. Before the above experiment (removing all the SAY in question) I was going to write..Yeah I thought the same, but then when I remove it, empty line should not be there. I've to repeat..
