However, I am wondering how to detect when the procedures for the

particular traveler-ID-number.? In the given example of a match,

If the count of the non-zero fields in the work order differs from the number of records in the traveler procedure file then they do not match.

are all of the columns Proc-4 through Proc-15 the NULL value? If

No, they are zero.

for example for the given work-order-number=1, if that row had
included Proc-4=1.04, then I presume that row would no longer be a
match for the set of TRAV#=123? Finally just to be sure, is each

Correct.

Proc-# column assured to correlate directly to the same #-value in
the Sequence-#; e.g. can Proc-3 be NULL, such that Proc-4 then
represents the Sequence#=3?

There will never be a zero procedure number field followed by a non-zero procedure number field.

I sorry I didn't think of these possibilities earlier. You are all so very thorough! Thanks!

if you want to understand why that is, there are many good books on
the design of operating systems. please pass them along to redmond
when you're done reading them :)
