Hi, I'm having a problem with what may be called variable "lifetime" or scope. Consider the two trivial scripts: <script1> scalar temp = 1 </script1> <script2> matrix temp = muniform(2,1) </script2> If I run both of them in this order, the second one gives an error, apparently because gretl doesn't like to put a matrix result into the scalar variable temp. Is this a reasonable behavior? If the commands were executed in a single console session or in a single file (including further called files or functions), I think yes. But if the commands live in separate script files that just happen to be executed in the same gretl session, I tend to think that gretl should do some sort of garbage collection when the end of a (main driver) script is reached. Or is it the official policy that the user should do a 'delete temp' at the end of any such script? (BTW, I know that the 'open' command clears gretl's workspace, which would probably be the solution here. But I find myself doing more and more with gretl's nice matrix language without opening datafiles. So maybe a 'clear' command is needed?)
