Quick HP42S question

Hi, all:

Just a quick HP42S question, as I don't have the manual at hand now and can't remember if it's even possible: How can you change the Polar/Rectangular mode programmatically ?

Manually from the keyboard is just a matter of setting the correct mode in the MODES menu, and programmatically you can test the current mode by checking whether Flag 73 is set or not.

But Flag 73 is a system flag and so it can't be set/cleared by the user. Are there some keywords that will change the mode from a running program (as part of an initialization procedure, for instance) ?

Sorry if this is a trivial question. Thanks.
V.
