Controlling Commenting

Another way of controlling output from a ChannelChannel is via the boolean (integer) CommentComment attribute, which controls whether comments are appended to describe the purpose of each value. Comment has the value 1 by default but, if set to zero, will suppress these comments. This is normally appropriate only if you wish to minimise the amount of output, for example:

astSet( channel, "Full=-1, Comment=0" );
nobj = astWrite( channel, skyframe );

might result in the following more compact output:

 Begin SkyFrame
    Naxes = 2
    Ax1 =
       Begin SkyAxis
       End SkyAxis
    Ax2 =
       Begin SkyAxis
       End SkyAxis
 IsA Frame
    System = "FK4-NO-E"
    Epoch = 1958
 End SkyFrame
