then added the indentation system,
ie. numtabs, indent(), outdent(), line().
seems to work so far.
still empty unions generated though.

not used to alter code gen yet.

also: TRUE and FALSE were wrong way round (oops)
and I have removed ABORT.. explicit error mesgs on stderr now.

renamed some procedures.
some silly little { onto new lines.
important change: added the print functions and prototypes.
