Topic: Lock a Lisp Routine

[BIGAL]

A simple way to add the lock routine to all your lisps there a DOS command that can help, you can copy two files together to make a third.

You make a batch file you change your serial number etc in one file then its simple
Copy serial+lisp1.lsp protlisp1.lsp
Copy serial+lisp2.lsp protlisp2.lsp

How to stop copying you cant but makes it difficult for them we used serial number and protect, got a phone call asking why the software would not work simple answer was trying to run on a friends computer without paying.

Using copy command in dos mode is a better way to  lock routines.There  is no way to decompile it.And "Copy serial+lisp1.lsp =protlisp1.lsp",this is a good idea.

Use AutoCAD's loginname as the password to activate the code.
I know it can be easily gotten around...but what a hassle to do so.
