st: re: WHILE command

How does one do this in cases where one cannot calculate, in advance,
the number of repetitions needed, or the list of items to be acted upon?

As Nick C has pointed out, nothing stops you from using a forvalues  
loop over a large number of values and testing within the loop to  
determine whether some condition is now satisfied (e.g., if the norm  
of the gradient is now less than epsilon), and using

continue, break

to terminate the loop at that point.
