Brute force answer:
Create 456 variables = 0.
Write 456 IF statements:
if STOP1 = 'a' and STOP2 = 'b' AB = 1.
if STOP2 = 'a' and STOP3 = 'b' AB = 1.
Improvements? I sure wouldn't want to type this out by hand, or have
or edit line by line -- too much room for error.

: Dear group
: Could someone help with this syntax task: We have 10 variables where each
: represents a tourist stop that people have taken on trips throughout their
: travels (eg Stop 1 where they stayed the 1st night, stop 2 where they stayed
: the 2nd night and so on). For each of these variables there are 30 possible
: destinations (these same 30 are value labels for each of the stops). We
: would like to gain data relevant to the number of times people travelled
: from point A to Point B (regardless of whether it may have been from Stop 1
: to 2 or Stop 9 to 10) as well as times (ie frequency of trips) travelled
: from Point B to Point A. Further this needs to be repeated for all possible
: combinations within the 30 destinations (= 465 combinations). Is there some
: syntax command that might abbreviate this task (perhaps LOOP or VECTOR?)
