ARexx Error Codes
Lister handles are the actual address in memory of the lister structure.
Opus 5 will reject any non-valid handles with an RC of 10.
All commands that return data return it in RESULT (with the exception of
dopus getstring , dopus getdesktop and lister getstring ) or a specified
(stem) variable; if an error occurs, the error code is returned in RC .
An RC of 0 generally indicates that everything is ok.
Error codes are:-
1 RXERR_FILE_REJECTED
The file you tried to add was rejected by the current lister
filters.
Note that this is not an error, just a warning. The file is still
added, it will just not be visible until the filters are changed.
5 RXERR_INVALID_QUERY
RXERR_INVALID_SET
The query/set item you specified was invalid.
6 RXERR_INVALID_NAME
RXERR_INVALID_KEYWORD
The filename or keyword you specified was invalid.
8 RXERR_INVALID_TRAP
The trap you tried to remove didn't exist.
10 RXERR_INVALID_HANDLE
The lister handle you gave was invalid.
12 RXERR_NO_TOOLBAR
The lister has no valid toolbar.
15 RXERR_NO_MEMORY
There wasn't enough memory to do what you wanted.
20 RXERR_NO_LISTER
A lister failed to open (usually because of low-memory).
You can convert the error codes returned in RC into meaningful error
messages (for error reports and so on) with the dopus error command.
