Dear all,

To reproduce

<hansl

function void testfun (scalar x, int n[1::1],list z[null], string s[null])

isn = exists(n)

print isn

isz = exists(z)

print isz

iss = exists(s)

print iss

end function

nulldata 1

series z1 = 1

series z2 = 2

list zz = z1 z2

testfun(1)

testfun(1,1)

testfun(1,1,z1)

testfun(1,1,zz)

testfun(1,1,zz,"a")

hansl>

The behavior of exists() with strings is different.

The more, there's difference across data types

but not across the situations.

Is this a bug or I missed something from the help?
