Help with simple conditional?

[Fairlight]

Someone told me 'co' may not work in processing.  Okay, so I tried a
different method that should work:

I've tried putting both the lookup value and the search value into ALLUP
variables and checking for INSTR eq "0".

If: instr(SinUp,SinSearch) eq "0"
Then: getnext sintest;goto loop

If I use that, and that -should- mean that the substring was not found, get
the next record and loop...it fails to work properly.  If I flip it to
"ne", it always passes, if I leave it as "eq", it always fails.  It should
succeed when there's a match, and it doesn't.

I've tried logging the values of SinUp, SinSearch, and INRes (INRes being
the result of an instr(SinUp,SinSearch).  Here's what I get:

sinup: 35000 (SINGLE MIX) searchup: DARK inres: 0
sinup: 35000 (SKYHIGH MIX) searchup: DARK inres: 0
sinup: BEFORE THE DAWN searchup: DARK inres: 0
sinup: BITTERSWEET MEMORY searchup: DARK inres: 0
sinup: BRING THE DARK (DARKDANCE MIX) searchup: DARK inres: 0
sinup: BRING THE DARK (SINGLE MIX) searchup: DARK inres: 0
sinup: CRACKHEAD KITTY searchup: DARK inres: 0
sinup: CRACKHEAD KITTY (CATNIP MIX) searchup: DARK inres: 0
sinup: DEMONS EVERY DAY (INSTRUMENTAL MIX) searchup: DARK inres: 0
sinup: DESPAIR (SINGLE MIX) searchup: DARK inres: 0
sinup: FALLING INTO YOU (INSTRUMENTAL MIX) searchup: DARK inres: 0
sinup: FOUR AM (INSTRUMENTAL MIX) searchup: DARK inres: 0
sinup: FUGUE STATE (INSTRUMENTAL MIX) searchup: DARK inres: 0
sinup: INTERLUDE 1 searchup: DARK inres: 0
sinup: INTERLUDE 2 searchup: DARK inres: 0
sinup: LYA (INSTRUMENTAL MIX) searchup: DARK inres: 0
sinup: MISCHIEF AND MAYHEM (SINGLE MIX) searchup: DARK inres: 0
sinup: NEON (INSTRUMENTAL MIX) searchup: DARK inres: 0
sinup: OWN THE NIGHT (INSTRUMENTAL MIX) searchup: DARK inres: 0
sinup: REGRETS (SINGLE MIX) searchup: DARK inres: 0
sinup: RELAXING MEADOW searchup: DARK inres: 0
sinup: SEASIDE CAVE searchup: DARK inres: 0
sinup: SKYHIGH INTERLUDE searchup: DARK inres: 0
sinup: SOLITARY ORBIT (SINGLE MIX) searchup: DARK inres: 0
sinup: SUNRISE (FAIRLIGHT MIX) searchup: DARK inres: 0
sinup: SUNRISE (INSTRUMENTAL MIX) searchup: DARK inres: 0
sinup: TWILIGHT (FAIRLIGHT MIX) searchup: DARK inres: 0
sinup: TWILIGHT (INSTRUMENTAL MIX) searchup: DARK inres: 0
sinup: VACATIANUS TROPICALUS (SINGLE MIX) searchup: DARK inres: 0
sinup: WEEKENDER (SINGLE MIX) searchup: DARK inres: 0

Okay, please explain to me how "BRING THE DARK" (both mixes) fail to
trigger a substring match against "DARK".  Hell, one has the word in it
-twice-.  Both 'co' and 'instr()' are acting improperly.  Both fields
involved are now ALLUP, and it's just flat-out failing.

This makes less and less sense.  It makes even less sense when you realise
that I have 'instr()' working in a table called from this one.  It's not
like I've never used instr() before...  So I know instr() works on these
binaries in general.  But what's going on with these comparisons?
