Problem using (command "Insert" fname ^C) in Autolisp routine

[rharris51]

We are trying to make an old lisp routine for automatically redefining detail blocks work under AutoCAD 2005. The following instruction now fails and interrupts the routine when it executes but does not find a matching filename:

(command "insert" fname ^C)

It's a very simple command and it still works when it finds the file it is looking for - but now it crashes the whole routine when fname is not found in the path.

It exits the lisp routine after displaying the search path and the last line displayed is *Invalid*.

Is there a flag or switch that needs to be set to make this command work the ways it did under older versions? Any workarounds or quick solutions?

Try this.

(if (findfile fname)
   (command "insert" fname ^C)
   (alert "\nFile not found")
 )

Just an observation. The ^C thingie should be changed to nil (^C is seen as a symbol that just happens to be nil when the call is made but it has no real meaning)

You can also try this.

(command "insert" fname \E)

That is the same as Stig's reply because (command nil) = (command)

You better include the folder (which contains the required file) in your "support file search path" and then run the programme.
