Pass lisp variable to batch file that requires arguments

[Anonymous]

I have a batch file i am calling from a lisp. It requires an argument that I want to pass from the lisp. How do I do this? I'm using the (startapp "filename.ext") function to call the batch file from a lisp.

[TheCADnoob]

is it something that can be passed like a file switch?

You could add some code to your lisp routine that will write a new temporary batch file containing a call to the main batch file with the arguments you want and then execute the temporary batch file using AutoCAD's SHELL command.

You did not specify the name of your batch file or the nature of the arguments you wanted to pass to it so here is a generic example with 2 arguments stored in variables:

(setq file_id (open "c:\\your path\\your temp batch.bat" "w"))
(write-line (strcat "\"c:\\your path\\your batch.bat\" " your_first_argument_string " " your_next_argument_string) file_id)
(close file_id)
(command "shell" "\"c:\\your path\\your temp batch.bat\"")
