Before we can create a FrameSet, we must have a Frame of some kind to put into it, so let's create a simple one:
INCLUDE 'AST_PAR'
INTEGER FRAME1, STATUS
STATUS = 0
...
FRAME1 = AST_FRAME( 2, 'Domain=A', STATUS )
We have set this Frame's Domain attribute () to
A so that it will be distinct from the others we will be using. We can
now create a new FrameSet containing just this Frame, as follows:
INTEGER FRAMESET
...
FRAMESET = AST_FRAMESET( FRAME1, ' ', STATUS )
So far, however, this Frame isn't related to any others.
