Re: if statement not working

This, in my not so humble opinion, is one of RDS's lesser decisions.

For some reason, not quiet explained yet, RDS decided that sequences must not
allowed to be compared
using the normal comparision operators. For sequences you are forced into
calling a function to
compare them. The two main functions are 'compare()' and 'equal()'.

  compare(s1,s2) returns one of three values:
    -1  if s1 is less than s2
     0  if s1 equals s2
     1  if s1 is greater than s2

  equal(s1,s2) returns one of two values:
     0 if s1 is not equal to s2
     1 if s1 is equal to s2

Go figure! Many people have been try to get RDS to see sense in using the
standard comparision
operators with sequences but to no avail yet.
