Looping Slide States

[David McFarlane]

Raghav,

Using a Goto (probably with an If-Then) seems like a perfectly good way 
to do this in E-Prime.  If you felt better using a more standard "Do... 
Loop Until" loop or the like, then you could put the "Do..." in an 
inline at the start of the loop, and the "Loop Until..." in another 
inline at the end of the loop, but that might look a little weird to 
other EP programmers.

Alternatively, sometimes when I want to do a repeating loop in E-Prime I 
just do it with another List.  I put the objects that I want to loop 
into a Procedure, and put that Procedure in a List with one row.  I can 
use the Weight to run the loop a specific number of times, or run the 
List with an arbitrarily high Weight or Terminate condition and use 
inline code (List.Terminate) to programmatically end the loop.

Just weighing in with more ideas for the E-Prime toolbox.
