RE: Trivia: How many lines of code are allowed in an RPG Program?

Frank,

  One way would be to write each of your 608,400 combinations into a data
file, (in sequential order of course) then chain to the record and see if
the record number is one more than the last one.

~~~~~~~~~~~~~~~~~~~~

Another way would be to only check one character at a time.   
First determine how many characters you need to check.
  i.e.

  Select;
  When zip1.first5chars = zip2.first5chars;
    charsToCheck = 6;
  When zip1.first4chars = zip2.first4chars;
    CharsToCheck = 5;
  Ect

  EndSelect;

  Exsr Check Chars;


  BegSR Chars;
    For I = CharsToCheck to 6;
      // perhaps you know, but since I don't I have to check to see if this
// is a numeric column or character.
      // then do a lookup on the zip1 column and the zip2 column.
      If result2 - result1 = 1
        // see footnote*
        Do your processing;
      Else;
        Not in order;
      EndIf;
    EndFor;
  EndSr;

*  I was going to say that you'd have to check for a change from 9 to 0 or
from Z to A, but now that I think about it, whenever that happens, in order
for it to be in sequence there should have been a change in the previous
column.  You should only have to actually check one column for in-sequence.
Every following column should be a rollover (9-0 or Z-A) and if it isn't,
then the records aren't in sequence.

Unless, of course, some zip codes are skipped.
