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? Federico
