Chad - Not that I know of, but I think I have hacked something
together before using the shift operator to tell you which elements
are adjacent. For example:

x=[1,2,3,4,5,17,45,46,47,48,49,50,51,59]

dx=(x-shift(x,1))[1:*]
print,dx
1 1 1 1 12 28 1 1 1 1 1 1
8
; then you can figure out which ones require special attention:

l=where(dx ne 1)
; the following prints the last element in a seqeuence that can be
; connected by a hyphen
print,x[l]

; but I think that handling all the special cases could be a nightmare!
Post your best solution! This is offered as just a start.
