BASIC is a room.

To (line - number) PRINT (msg - text): (- .basic_{line}; print (TEXT_TY_Say) {msg}; new_line; -).

To (line - number) GOTO (dest - number): (- .basic_{line}; jump basic_{dest}; -).

When play begins:
	10 PRINT "Hello.";
	20 GOTO 40;
	30 PRINT "This is never printed.";
	40 PRINT "Goodbye.";
