Move - copy bytes of data from a source to a destination system unit

procedure Move ( const SourcePointer; var DestinationPointer; CopyCount : Integer ) ; Description The Move procedure is a badly named method of copying a section of memory from one place to another. CopyCount bytes are copied from storage referenced by SourcePointer and written to DestinationPointer It can be used to take a copy of a substring from one string and overlay it on top of part of another string. If copying from the current string to another part of the same string, then Copy works intelligently, preserving data where appropriate. Notes The original data is always preserved, unless moving fronm and to the current string - so Move is not very informative. There is no checking on the referenced storage areas - be careful about all direct storage operations such as this.
