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..
