Various other facilities related to the graphics database exist as well as those described in the previous section. This section gives a brief description of a few more:
% piclabel fred
will give the label FRED to the current picture. This picture could be made current again at a later time by re-selecting it using PICSEL:
% picsel fred
Any label associated with a picture is displayed in the list produced by PICLIST.
% picdef mode=a prefix=spec xpic=3 ypic=4
The bottom-left picture would be labelled SPEC1 and the rest are numbered in sequence from left to right to SPEC12--the top-right picture. You'd call PICSEL to select each picture in turn via a while loop in a C-shell script. Since this is a common operation a shorthand command, PICGRID, is available. For instance:
% picgrid 3 4
is equivalent to the previous example, except that the pictures are labelled 1 to 12.
% gdstate
Status of the xwindows window graphics device...
The current picture is a FRAME picture.
