+exec -- get keyboard input from a file
+
+syntax:  exec <pathname>
+
+ex:      exec foo.bar
+
+Makes keyboard input come from the specified file until an 
+error occurs or until end of file is reached.  Wildcards are 
+allowed.  The file must be of type TXT ($04), SRC ($B0),
+or $C6/$8001 (Davex 8 Script).
+
+If %autoexec exists, Davex automatically execs it on entry.
+(If another pathname is passed to Davex in its startup buffer,
+Davex attempts to exec the specified file instead of %autoexec.)
+
+Command prompts and commands will not appear on the screen
+while the file is being exec'ed (but the commands DO get
+stored in the History buffer, so you can use the up arrow to
+see what commands were executed; this is useful if an error
+occurs during the exec).
+
