Subject: mimicking the CCP

Hi, all.  I ran into the problem recently of doing a load and go on a random
text editor in a manner that was transportable to any CP/M system. As it
turned out, I was able to do this with Vedit, but not with the standard
editor, ED.

ED, it seems, does not like being loaded by anything but the CCP.  It won't
go under DDT, and it sure as heck won't go under my program. I tried to
duplicate all the documented entry conditions: dma pointed to 0080H, the
command line buffer filled with the file name, and the default FCB at 005CH
set up properly.  I even kept the CCP around, as well as CCP's stack
pointer, although it looks as though ED doesn't care about that.

I'd like to know if this problem crops up on CP/M systems other than
an Apple II using the Microsoft Softcard (2.20B), and if so, whether
there is a cure.  If any of the suggested cures work (assuming there
are some), I will post 'em to the net or otherwise find some way
of making them available.  Thanks.
