PRIN

PRIN

(prin stream &rest forms)

stream is a subtext stream;

forms are evaluated in context and result is output, except the following two forms are handled specially:

(tg tagid &rest forms)

tagid resolves to a string or a gtk-text-tag

(pr class init &rest forms)

class is a pres-derived class;

init is a list spliced into (make-instance 'class ...) form to create the presentation

Note: Inside prin, forms are evaluated and results printed. Except, if the form returns NIL, it is invisible. The macro (prog0 &body body) is provided for your convenience.
