Mike meant NES( ), not EQS( ).
and SUMMATION( ), not SUM( ).
SUM( ) won't yield a scalar unless all delimiters are the same.
ResultArray = NES(Array1, Array2)
If summation(ResultArray)=0 then samething = true else samething
= false
Which is all well and good . . . as long as you consider "7" = "7.00" =
"007" = " 7."

To address Bill Brutzman's original question:
The trouble is that we don't _declare_ variables in UV/UD/MV Basic as
strings or integer, etc.
So UV & its kin makes a best guess.
UV (& kin? There may be some variance!) will attempt to compare EQ, NE,
GT, & their ilk the two vars numerically, if possible.
That's what happens with my "seven" example above. All those strings
are treated as equal numerically.
The related multivalue handling functions, .e.g, EQS, do the same, piece
by piece.
If one of the two vars can't be treated numerically, then it compares as
strings.
This is probably as good a general solution as any using "EQ":
if len(Array1) EQ len( Array2 ) then ; * because len( )
is so very fast
* non-numeric 'x' concatenation forces the 2 to be treated as
strings:
samething = ( ( 'x': Array1 ) EQ ( 'x': Array2 ) )
end else
samething = @false
end
i don't know how the speed compares to COMPARE(), which is simpler to read.

I'm not sure this would work, as the UniData documentation for "EQS"
states:
The UniBasic EQS function compares each value in array1 to its
corresponding
value in array2. UniData returns an array with 1 in each position
where values are
equal, and 0 in each position for values that are not equal.
Thus, if the following...
ARRAY1 = '11':@VM:'12':@VM:'13':@VM:'20':@VM:'21'
ARRAY2 = '11':@VM:'12':@VM:'13':@VM:'19':@VM:'22'
ARRAY3 = EQS(ARRAY1,ARRAY2)
...then the resultant ARRAY3 would look like:
'1':@VM:'1':@VM:'1':@VM:'0':@VM:'0'
On the other hand, the following...
ARRAY1 = '11':@VM:'12':@VM:'13':@VM:'20':@VM:'21'
ARRAY2 = '11':@VM:'12':@VM:'13':@VM:'20':@VM:'21'
ARRAY3 = EQS(ARRAY1,ARRAY2)
...would assign ARRAY3 to look like:
'1':@VM:'1':@VM:'1':@VM:'1':@VM:'1'
...and:
SUM(ARRAY3)
...would equal 5, which would only indicate equality if
SUM(ARRAY3) = DCOUNT(ARRAY3, @VM)
Does this make sense? With mixed @AMs & @VMs I suspect one would have
to loop through the result array comparing.
Is UniData different than UniVerse?

Try:
ResultArray = EQS(Array1, Array2)
If sum(ResultArray)=0 then samething = true else samething = false
