[net.micro.pc] BASIC Protected Mode

ruth@houxa.UUCP (R.LEWART) (01/03/84)

Does anyone out there know how to crack this mode
(loaded by a SAVE "...",p )?   I think it can be done
via a poke in the area 400-5FF.   Thanks,
Ruth Lewart, ...houxa!ruth

The following comes from the October '83 issue of PC World:

BASIC Unprotect
This series of commands will let you list a program that has been saved
with the `,p' option.  From DOS type BASICA or BASIC.  Once in BASIC type
in NEW <ENTER> ; then type DEF SEG <ENTER>.  Now type BSAVE "UN.P",1124,1
<ENTER> ; load the protected program; and type BLOAD "UN.P",1124 <ENTER>.
Now fell free to LIST, SAVE, or EDIT the protected program.  To protect
a program before saving it type DEF SEG:POKE 1124,255.
