Hi everybody,

I noticed this little thing

<hansl>

clear
set verbose off

function scalar increment(scalar *n)
    n += 1
    return n
end function

n = 0

print "printf:"
printf("%d\n", increment(&n))

print "eval:"
eval increment(&n)

print "print:"
print increment(&n)

</hansl>

<output>

printf:
1
eval:
2
print:
4

</output>

As you can see, seem like that "print" command calls the function twice.

Is it something wanted?
