■ Loads an existing form (.FRM) or code (.BAS) module into
  memory and adds it to your project. Files already open
  remain in memory.
 
■ Tips:
    • Use New Module rather than Add File to create and add
      a code module to your project.
    • Use New Form to add a form module to your project.
 
■ To load an existing module:
    1. Type a file name in the File Name text box,
                  ┌────────────────────────┐
       File Name: │ *.BAS                  │
                  └────────────────────────┘
       • Only files ending with .BAS are displayed in the
         Files list box, since the default wildcard
         specification is *.BAS for code modules.
 
       • To display other file types, type a different
         wildcard in the File Name text box. For example,
         *.FRM displays all files ending with .FRM (all
         form modules) in the current directory.
 
       or select a file name from the Files list box.
 
        Files:
       ┌──────────────┐
       │ JONES.BAS    ↑
       │ MY.BAS       ░
       │ OLD.BAS      ↓
       └──────────────┘
 
    2. Choose the file type.
 
       ┌File Type───────────────────────────────────────────┐
       │ (•) Module [*.BAS]      ( ) Include File  [*.BI]   │
       │ ( ) Form   [*.FRM]      ( ) Text File     [*.TXT]  │
       └────────────────────────────────────────────────────┘
       • You cannot add a binary file as an include (.BI) or
         text (.TXT) file. Binary files can only be added as
         form (.FRM) or code (.BAS) modules.
 
    3. Press Enter or choose Edit in Active to edit the new
       module in the active window,
       ╔══════════════╗
       ║Edit in Active║
       ╚══════════════╝
       choose Edit in New to edit the new module in a new
       window,
       ┌──────────────┐
       │  Edit in New │
       └──────────────┘
       or choose one of the following:
       ┌───────────────┐
       │     Cancel    │ To cancel the operation
       └───────────────┘
       ┌───────────────┐
       │      Help     │ To get help
       └───────────────┘
 
■ The Directories list box provides access to other drives and
  directories:
 
   Directories:
  ┌──────────────┐
  │ ..           ↑ • Include a drive/path designation with the
  │ [-A-]        ░   file name
  │ [-C-]        ░
  │              ↓ • Choose the appropriate drive/directory
  └──────────────┘
