link_elements

• type: setup command.
• function: assert a link between parameters of accelerator elements.

• target -- The name of the elements to be modified by the link. May contain wild-cards.
• exclude -- Wildcard sequence to match to element names. If a match is found, the element is excluded from the link.
• item -- The parameter that will be modified.
• source -- The name of the elements to be linked to.
• source_position -- May be one of ``before'', ``after'', ``adjacent'', ``nearest'', or ``same-occurrence''.
• mode -- May be either ``dynamic'' or ``static''. A dynamic link is asserted whenever the source is changed (during correction, for example). A static link is asserted only when an error or variation is imparted to the source, and at the end of correction.
• equation -- An rpn equation for the new item value in terms of the item values for the source. The prior value of the item is on the top of the stack. To refer to the source parameter values, use the name of the parameters. These names must appear in capital letters.
