Example:

	GTM>DO ^%T
	8:30 AM
	

This example invokes %T, which prints the current time and does not set %TIM.

Example:

	GTM>DO INT^%T
	GTM>ZWRITE
	%TIM="8:30 AM"
	

This example invokes INT^%T, which sets the variable %TIM to the current time. ZWRITE displays the contents of the variable.

Example:

	GTM>WRITE $$FUNC^%T
	8:30 AM	
	

This example invokes FUNC as an extrinsic function, which returns the current time.
