In this context you are much better off not mucking about with strings (still less with @-style string substitution). Here's your example rewritten in a much simpler and more reliable form: <hansl> open australia.gdt scalar data2 = lastobs(PUS) scalar def_erro = 4 smpl data2-def_erro ; smpl full smpl ; data2 smpl full smpl data2-def_erro data2 print "Hello, World!" </hansl> That said, I'll take a look at the difference in behaviour between the last 1.9.92 and 1.10.0cvs. Allin
