oneway - error message

[wei hou]

just a new user of pspp. thanks for the software.

However, I keep getting the error message for the following syntax:

oneway VAR002 BY grp
 /plot means.


syntax:2: error: Syntax error expecting end of command at 'plot'.


and same error for

neway VAR002 BY grp
 /posthoc=scheffe.


syntax:2: error: Syntax error expecting end of command at 'posthoc'.


and then i tried 

 glm VAR002 by grp.

syntax:1: error: GLM is not yet implemented. 

Thank you very much,

Wei
