Formal Description:

A + @(A) - @(B) --> B.
   {Put in B the address, relative to B, of the location pointed at by A}

Informal Description

This instruction moves a pointer contained in A into B, adjusting it so that it continues to point to the correct location (see fig. 25). Normally, pointers should be copied with MVPT, and using MOVE instead is an error (beware: a rather insidious kind of bug!); anyway, there are circumstances in which you will prefer to use MOVE and adjust the pointer subsequently with RNPT.
