COPY/DKEY source_frame source_desc dest_key
	copy descriptor of source frame to keyword
\us\pu
Purpose:   
           copy descriptor of source frame (image or table) to keyword
\up\sy
Syntax:    
           COPY/DKEY source_frame source_desc dest_key
\ys\pa
           source_frame = name of source frame (image or table) 
\ap\pa
           source_desc = source descriptor
\ap\pa
           dest_key = name of destination keyword
\ap\no
Note:      
           If the destination keyword does not exist already, it is created
           with same type and (full) size as the source descriptor.
\\
           Default type of frames is an image, i.e. source_frame = lola
           will be interpreted as `lola.bdf', for tables you need always the
           file type as well in the name.
\\
           If only a few data values are copied, e.g. < 5 values, then it is
           more efficient to use the M$VALUE function to set the keyword to 
           the values of the descriptor.

Examples:
\ex
           COPY/DKEY tiburon ident/c/10/10 INPUTC
             Will copy the string in descriptor IDENT of frame `tiburon.bdf'
             (starting at the 10th element) to keyword INPUTC
             (starting in the beginning by default).
\xe \ex
           COPY/DKEY tiburon.tbl ident/c/10/10 INPUTC
             As above but table file `tiburon.tbl' is used.
