.Trad.Messages |

|
Informative messages, commands executed by rad, and errors |
| 1055 |
|
Other views may be accessed within rview using the "L name" |
| 1056 |
|
command, and new views can be added with the "V name" |
| 1057 |
|
command. |
| 1058 |
+ |
|
| 1059 |
+ |
When using the "V" command to change an existing view, do not |
| 1060 |
+ |
give it a name because the previous view will not be overridden. |
| 1061 |
+ |
Instead, give it a new name (or no name, which will show up as |
| 1062 |
+ |
a number later), then use the Views screen to override the previous |
| 1063 |
+ |
view definition with the new one. |
| 1064 |
|
(See the rview(1) man page and the "View" topic in the current |
| 1065 |
|
help category for more information.) |
| 1066 |
|
|
| 1077 |
|
If the special entry "ALL" is selected, then every view in the |
| 1078 |
|
current list will be rendered if it hasn't been already. |
| 1079 |
|
|
| 1080 |
+ |
The view menu next to the "rview" button will be disabled if there |
| 1081 |
+ |
is only one view to choose from. |
| 1082 |
+ |
The view menu next to the "Start" button will be disabled if there |
| 1083 |
+ |
is a batch job in progress, and thus the view cannot be changed. |
| 1084 |
+ |
|
| 1085 |
|
The batch rendering view menu also selects the view or views |
| 1086 |
|
to use in producing a script during a dry run. |

".err".) |

When a batch process is started or already running, this button |
| 1106 |

will be disabled. |

When a batch process is started or already running, or when a |
| 1106 |

process is on another host and its status is unknown, |
| 1107 |

this button will be disabled. |
| 1108 |
|
|
| 1109 |
|
The background process can be killed during this or later |
| 1110 |
|
invocations of trad using the "Kill" button. |
| 1111 |
+ |
If the process was started on another machine and the status is unknown, |
| 1112 |
+ |
it will be necessary to run trad from the other host or remove the error |
| 1113 |
+ |
file manually before starting a background process on this machine. |
| 1114 |
+ |
This is to protect you from the great confusion that results when two |
| 1115 |
+ |
machines are working from the same project file. |
