set options

If any options are specified then they set the global shell options for the current shell.
Preceding any boolean option by a + instead of a - will turn OFF that option.
Example
set +omit-xml-declaration

turns OFF the omit-xml-declaration option


set parameters

Sets the positional parameters or prints environment variables

Example: sets $1 to "foo" and $2 to "bar"
$ set foo bar


Positional parameters can also be XML expressions
$ set <[1,"foo",<bar>spam</bar>]>


print variables

With no arguments prints the names and types of all variables as an xml document.
Note this differences from the unix shells in that it doesnt print the variables value, this is because
values in xmlsh can be extremely large.
$ set
<env>
   <variable name="a" type="xml"/>
   <variable name="PATH" type="string"/>
</env>
