if binaryfld = -1 error.

Hey all,

I have a weird thing happening.   I'm comparing the null map of a
trigger buffer field to -1, and i'm getting:

"The target for a numeric operation is too small to hold the result "

relevant code:

* null byte array (23 fields)

d $nuller         s              2b 0 based($nullOffset) dim(23)
d $nullOffset     s               *   Inz(*Null)

* trigger buffer

d InBuffer        DS         32767
d  TgFile                       10
d  TgLibr                       10
d  TgMemb                       10
d  TgEvent                       1
d  TgTime                        1
d  TgLockLvl                     1
d  TgFiller1                     3
d  TgCCSID                      10u 0
d  TgFiller2                     8
d  TgOldOffset                  10u 0
d  TgOldLength                  10u 0
d  TgONulOfs                    10u 0
d  TgONulLen                    10u 0
d  TgNewOffset                  10u 0
d  TgNewLength                  10u 0
d  TgNewNulOfs                  10u 0
d  TgNewNulLen                  10u 0
d  TgFiller3                    16

.....

c                   eval      $nullOffset = %addr(InBuffer) + TgNewNulOfs

c                   if        $nuller(2) = -1
c                   eval      @RecNew.LVL2 = 0
c                   end

I get my error when it hits the above "IF" statement.

In debug, the value of $nuller(2) is -56

what up?   is there some sort of intermediate variable being created
to resolve $nuller(2) so it can be compared?

thanks,

Rick
