@item

If an environment variable @code{ASIR_RSH} is set,

the content of this variable is used as a promgram to invoke

remote servers instead of @var{rsh}. For example,

@example

% setenv ASIR_RSH "ssh -f -X -A "

@end example

implies that remote servers are invoked by @samp{ssh} and that

X11 forwarding is enabled. See the manual of @samp{ssh} for the detail.

@item

Some @var{command}'s consume much stack space. You are recommended

to set the stack size to about 16MB large in @samp{.cshrc} for safe.

To specify the size, put @code{limit stacksize 16m} for an example.

@code{open_canvas} opens a canvas, which is a window for drawing objecgts.

One can specifies the size of a canvas in pixel by

supplying @var{geometry} option [@var{x},@var{y}]. The default size is

[@code{300},@code{300}].

This function pushes an integer value onto the stack of the OpenXM server.

The value is used to distiguish the opened canvas and one has to pop

and maintain the value by @code{ox_pop_cmo} for subsequent calls of

@code{draw_obj}.
