You can store your Venapp scripts in a binary format. This is required for some of the redistribution options, but also makes modification difficult. To save a Venapp in Binary form open the Venapp script in the Venapp Editor or the Text Editor and select File>Save As, entering a file name with extension .vcf (Vensim Custom Format). The Venapp script saved in this format is not a text file. It can be run by opening from the File>Open Model command but cannot be modified. The binary format does not provide data security, but is some protection against accidental modification.
If you have included any PASSWORD controls, these will be written in an encrypted format to an arbitrary location in the .vcf file. It is not possible to recover the password from the .vcf file, though the .vcf file will open the password protected model.
You can load .vcf files with the File>Open Model command or when Vensim (or Vensim Application Runtime) is started, just as you can for .vcd files.
