Re: [Gretl-devel] problem with -= in a function

'time' is no exception here: y -= y.time will work (have just tested it). The exception is rather 'const', because your expression y -= const works although it's not given like 'y.const'. I guess the reason is that const has special properties, always being present in the dataset, having index 0 etc. cheers, sven
