Vensim Help

Several commands on the File menu work differently for the Text Editor.

Save As

Save As saves a copy of the file in the Edit window to another name.  You are prompted for a file name.  If the file name you select already exists, you are asked if you want to overwrite the file.  A new history file is started for the renamed file containing changes relative to the original file the last time it was saved.

If you use Save As to save a .vcd file to a file with the .vcf extension, the file will be saved as a binary Venapp description file.  Such files are somewhat faster to load than .vcd files and also a little more secure, but their main function is to create packaged applications.
