Tony, I have been working with your RECALL.BA from calls.mnu and RAMDIR.BA BUT
the location for MSPLAN given by RAMDIR (65535) produces an SN error. All the
rest work great.  Is there a trick to calling MSPLAN rom?  65535 being the
limit of ram would, I guess, cause a problem.  Hope you have a ready answer.
Looking forward to your talented solution to this one. THXS.

Yes.  The number listed in the RAM directory for MSPLAN is not really where
MSPLAN is located.  As a matter of fact, 65535 is 2^16-1, or the absolute last
byte in RAM space. Since no file can be located at that location, the
operating system takes that as a flag to set the ROM selection switch and
enter the ROM. But because it's a flag, you can't ENTER the option ROM there,
you have to do a CALL, as documented by the company that produced the ROM, to
get into it.

Your mention of using RECALL indicates you are playing around with making
various program names invisible or visible on the menu.  I don't know what
version of RECALL you have, but it may be that you're trying to work with the
version for the 100/102 in a 200. Anyway, if you're attempting to make MSPLAN
invisible, you have to change the value of the attribute byte, which is stored
at the address indicated in the first column - at 62089.  Poking 248 to that
address makes MSPLAN invisible, and you won't be able to enter MSPLAN from the
menu in that bank.  Poking 240 to 62089 makes the name visible on the menu
again, and restores access from the menu.

Does that answer your question?  If not, can you be more specific about what
you're trying to do?

Tony, it was a M100 version that I changed by revising the pokes to those of
the M200.  RAMDIR.BA gave me the locations of the ROM programs.  Making TEXT,
ADDRS,SCHEDL,MSPLAN invisible, they are then called by RECALL.BA EXCEPT
MSPLAN.  That call produces SN error in line(the line referring to MSPLAN). As
you know theM200 has MSPLAN built in.  Is there a version of RECALL for the
M200 that overcomes this problem?  I'm hoping you have a workaround for this
or you can relay a method of accessing builtin MSPLAN rom from RECALL.BA.
Thanks for your continued support of the portables and M100SIG. /EXIT

Jim - You can get into MSPLAN from BASIC with...

      CALL27801,1+(INP(216)AND12)

Paul,
 Why is the ",1+(inp(216)and12)" necessary for the MSPLAN call? On occasion
I've just made the CALL27801 and it seemed to work all right.

Randy - I was just a bit overly cautious.  I just disassembled the ROM at
27801 and I see that the ROM code does that, so a simple CALL 27801 should
suffice.
