Protect EXE's

[Thomas Diehl]

Hello,
i am looking for a way to protect my own EXE files
writen in pb 3.2/3.5 against disassambling.

There are several freeware tools that do their job.
But when i chain from myprog1.exe to myprog2.exe
and back - i receive error 206 "not a pb program"

thanks for any idea - Thomas

Such tools damage the chain file format. If you want to use them,
you'll need to redesign your programs to use RUN instead of CHAIN.

You may want to 'pack' your exe ... I use UPX which can be
uncompressed by anyone, still my goal is compression. There maybe executable packers around
that allow you to specify a password for unpacking.

Best regards,

Tom,

thanks for the reply.
But after changing all my progs to exe's,
it is not possible to jump forward and backward
wit the run command.
Same error saying ...: "not a child of basic"

Ok. The compiler must be doing a safety check to make sure that the
target file is a PB/DOS executable. Replace RUN with EXECUTE and you
should be all set.
