number of iterations

Hi Folks,
Is there a way to count the number of iterations in a Repeat.. Until
Loop?

thanks

I suppose something like "count =+" would work. ;-)

Cheers,

David

How can I do that in this example? I would like to have print the
number of iterations within that Repeat Loop.

Thanks
;E1 = Unit vector, known
; Z is known matrix
REPEAT BEGIN
EC = Z##E1
L = sqrt(EC[0]+EC[1])
E1 = EC/L
print,L
;Keep going until nothing is moved.
ENDREP UNTIL L LT 1.2840277

;E1 = Unit vector, known
; Z is known matrix
count = 0
REPEAT BEGIN
print, count++
EC = Z##E1
L = sqrt(EC[0]+EC[1])
E1 = EC/L
print,L
;Keep going until nothing is moved.
ENDREP UNTIL L LT 1.2840277
