What is the "!!" in the first GET for? One "!" would convert to upper, but why two?

I can't figure out what the ";" is for in the second button.
Or what the "IV" portion of the PICTURE is doing.

The FUNCTION in the last two don't seem to match the codes in the help. What would "pupdhe" and "pdae" be for? Are the variables maybe?

@ 03 * row_incr + row_plus, 58 GET new_rem ;
	PICTURE '!!' VALID v_find( .T. )
@ 08 * row_incr, 02 GET choice ;
	PICTURE '@*IV ' + REPLICATE( ';', max_view - 1 ) ;
	SIZE 1, 76, 0 ;
	WHEN rem_cnt >= _CUROBJ - 1 ;
	VALID pullrem()
@ 02, 02 GET choice ;
	FUNCTION pupdhe;
	SIZE but_height, but_width, 1 ;
	VALID rec_rem() ;
	DEFAULT( 1 )
@ 03 * row_incr + row_plus, 02 GET edit_del ;
	FUNCTION pdae ;
	SIZE 1, radio_width, 1 ;
	VALID v_edit_del() ;
