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.
