Under DOS 3.3 there are several reasons why the 'BRUN' command can cause problems if used within an Applesoft program. It's always better (read 'safer') to use the BLOAD/CALL sequence. There's an excellent discussion of exactly what happens in the June 1986 issue of Apple Assembly Line. The article was written by Bob Sander-Cederlof. If you're still clinging to DOS 3.3, and need that info, back issues may be available from him, although the newsletter is no longer published. The last address I have is: S-C Software Corporation PO Box 280300 Dallas, TX 75228 (214) 324-2050 That info may not still be valid - publication of the newsletter ceased almost a year ago. One of the main reasons for using 'BRUN' is that the load/execution address of the file may not be known. There is a way around this, though, and it was also mentioned in the same publication, in the August 1986 issue. BLOAD <filename> and then CALL 41876 It's not necessary to know the load address if it's done that way. Before you rush off and try this -- remember, we're talking DOS 3.3 here!!
