Usability suggestion: since this is a VM-specific widget, could you return codes that are consistent with the implementation of DIAG 8 on CMS? I think it would help in understanding how to use the gadget, and folks coming over from CMS would be more familiar with those return codes. > If there is a consensus that vmcp should always print > something to stderr if the buffer was not large enough, tell > us and we can add that. A combination of the "familiar" return codes noted above, and an explanatory message to stderr would be my preferred approach. -- db ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
