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.
Load/Load Custom/Run Venapp/Run Command/Dat2VDF
Load takes the model in the Text Editor and loads it into the Workbench. This option is only available when Vensim is in off-line mode. Otherwise, the model you are working with in the Text Editor is automatically loaded into the Workbench. If necessary, load will first check the model.
Load Custom takes Custom Graph descriptions and loads them into Vensim for use in the Custom Graph control. Any errors are reported in a separate error window.
Run Venapp‡ runs the file as a Vensim application. Errors, if detected, will be reported in a separate window. You will be given the opportunity to abort the operation.
Run Command‡ runs the file as a Vensim command script. Errors, if detected, will be reported in a window and you will be given the opportunity of aborting the operation.
Dat2VDF converts the data in the file into a .vdf file. The new file will have the same name as the file with which you are working but with the .vdf extension. If this file exists, you will be queried for the name of the .vdf file you want to create. An error window will appear showing any error detected, and what data were written.
